DS21811C-page 9 MCP6281/2/3/4/5 3.0 APPLICATION INFORMATION The MCP6281/2/3/4/5 family of op amps is manufactured using Microchip's state of the art CMOS process. This family is specifically designed for low-cost, lowpower and general-purpose applications. The low supply voltage, low quiescent current and wide bandwidth makes the MCP6281/2/3/4/5 ideal for battery-powered applications. 3.1 6 4 ( Maximum expected V IN ) - V DD R IN ---------------------------------------------------------------------------------2 mA V SS - ( Minimum expected V IN ) R IN -----------------------------------------------------------------------------2 mA 2 3.3 1 0 -1 FIGURE 3-2: Resistor (RIN). -15 -14 -13 -12 -11 -10 -9 -8 -7 -6 Input Current Limiting Rail-to-Rail Output The output voltage range of the MCP6281/2/3/4/5 op amp is VDD - 15 mV (min.) and VSS + 15 mV (max.) when RL = 10 k is connected to VDD/2 and VDD = 5.5V. Refer to Figure 2-16 for more information. VOUT VIN 3 + VIN 3.2 VDD = 5.0V G = +2 V/V 5 VOUT MCP6281 RIN Rail-to-Rail Input The MCP6281/2/3/4/5 op amp is designed to prevent phase reversal when the input pins exceed the supply voltages. Figure 3-1 shows the input voltage exceeding the supply voltage without any phase reversal. Input, Output Voltage (V) - -5 Time (1 ms/div) FIGURE 3-1: The MCP6281/2/3/4/5 Show No Phase Reversal. The input stage of the MCP6281/2/3/4/5 op amp uses two differential input stages in parallel. One operates at low common mode input voltage (VCM), while the other operates at high VCM. With this topology, the device operates with VCM up to 300 mV above VDD and 300 mV below VSS. The Input Offset Voltage is measured at VCM = VSS - 300 mV and VDD + 300 mV to ensure proper operation. Input voltages that exceed the input voltage range (VSS - 0.3V to VDD + 0.3V at 25C) can cause excessive current to flow into or out of the input pins. Current beyond 2 mA can cause reliability problems. Applications that exceed this rating must be externally limited with a resistor, as shown in Figure 3-2. MCP6283/5 Chip Select (CS) The MCP6283 and MCP6285 are single and dual op amps with chip select (CS), respectively. When CS is pulled high, the supply current drops to 0.7 A (typ) and flows through the CS pin to VSS. When this happens, the amplifier output is put into a high-impedance state. By pulling CS low, the amplifier is enabled. If the CS pin is left floating, the amplifier may not operate properly. Figure 3-3 shows the output voltage and supply current response to a CS pulse.

MCP6281/2/3/4/5 3.4 Cascaded Dual Op Amps (MCP6285) 3.5 The MCP6285 is a dual op amp with chip select (CS). The chip select line is available on what would be the non-inverting input of a standard dual op amp (pin 5). This feature is provided by connecting the output of op amp A to the non-inverting input of op amp B, as shown in Figure 3-4. The chip select line, which can be connected to a microcontroller I/O line, puts the device in Low Power mode. Refer to Section 3.3 "MCP6283/5 Chip Select (CS)". VINB- VOUTA/VINB+ 1 VINA- VINA+ 6 2 3 B A 7 VOUTB Capacitive Loads Driving large capacitive loads can cause stability problems for voltage feedback op amps. As the load capacitance increases, the feedback loop's phase margin decreases and the closed-loop bandwidth is reduced. This produces gain peaking in the frequency response, with overshoot and ringing in the step response. A unity-gain buffer (G = +1) is the most sensitive to capacitive loads, though all gains show the same general behavior. When driving large capacitive loads with these op amps (e.g., > 100 pF when G = +1), a small series resistor at the output (RISO in Figure 3-5) improves the feedback loop's phase margin (stability) by making the output load resistive at higher frequencies. The bandwidth will generally be lower than the bandwidth with no capacitive load. MCP6285 - CS VIN + VOUT CL Cascaded Gain Amplifier. The key issue to note from this configuration is that the output of op amp A is loaded by the input impedance and input offset current (IOS) of op amp B. The input impedance of the op amp is typically 1013||6 pF, as specified in the DC specification table (Refer to Section 3.5 "Capacitive Loads" for further details regarding capacitive loads). An IOS of 15 pA at +85C and 500 pA at +125C (VDD = 5.5V) sinks into the output of op amp A. This is shown in Figures 2-5 and 2-12. The common mode input range of these op amps is specified in the data sheet as VSS - 300 mV and VDD + 300 mV. However, since the output of op amp A is limited to VOL and VOH (20 mV from the rails with a 10 k load), the non-inverting input range of op amp B is limited to the common mode input range of VSS + 20 mV and VDD - 20 mV. FIGURE 3-5: Output Resistor, RISO stabilizes large capacitive loads. Figure 3-6 gives recommended RISO values for different capacitive loads and gains. The x-axis is the normalized load capacitance (CL/GN), where GN is the circuit's noise gain. For non-inverting gains, GN and the Signal Gain are equal. For inverting gains, GN is 1+|Signal Gain| (e.g., -1 V/V gives GN = +2 V/V). 1,000 Recommended R ISO () FIGURE 3-4: RISO MCP6281 5 100 GN = 1 V/V GN = 2 V/V GN 4 V/V 10 10 100 1,000 10,000 Normalized Load Capacitance; CL / GN (pF) FIGURE 3-6: Recommended RISO values for Capacitive Loads. After selecting RISO for your circuit, double-check the resulting frequency response peaking and step response overshoot. Modify RISO's value until the response is reasonable. Bench evaluation and simulations with the MCP6281/2/3/4/5 SPICE macro model are very helpful. 2004 Microchip Technology Inc. DS21811C-page 11 MCP6281/2/3/4/5 3.6 Supply Bypass 3.8 With this family of operational amplifiers, the power supply pin (VDD for single-supply) should have a local bypass capacitor (i.e., 0.01 F to 0.1 F) within 2 mm for good, high-frequency performance. It also needs a bulk capacitor (i.e., 1 F or larger) within 100 mm to provide large, slow currents. This bulk capacitor can be shared with other parts. 3.7 The easiest way to reduce surface leakage is to use a guard ring around sensitive pins (or traces). The guard ring is biased at the same voltage as the sensitive pin. An example of this type of layout is shown in Figure 3-7. VIN- VIN+ VSS Guard Ring FIGURE 3-7: for Inverting Gain. 2. 3.8.1 SALLEN-KEY HIGHPASS FILTER The MCP6281/2/3/4/5 op amps can be used in activefilter applications. Figure 3-8 shows a second-order Sallen-Key highpass filter with a gain of 1. The output bias voltage is set by the VDD/2 reference, which can be changed to any voltage within the output voltage range. PCB Surface Leakage In applications where low input bias current is critical, printed circuit board (PCB) surface leakage effects need to be considered. Surface leakage is caused by humidity, dust or other contamination on the board. Under low humidity conditions, a typical resistance between nearby traces is 1012. A 5V difference would cause 5 pA, if current-to-flow, which is greater than the MCP6281/2/3/4/5 family's bias current at 25C (1 pA, typ.). 1.

This filter, and others, can be designed using Microchip's FilterLab(R) software, which is available on our web site (www.microchip.com). 3.8.2 INVERTING MILLER INTEGRATOR Analog integrators are used in filters, control loops and measurement circuits. Figure 3-9 shows the most common implementation, the inverting Miller integrator. The non-inverting input is at VDD/2 so that the op amp properly biases up. The switch (SW) is used to zero the output in some applications. Other applications use a feedback loop to keep the output within its linear range of operation. Example Guard Ring Layout For Inverting (Figure 3-7) and Transimpedance Amplifiers (convert current to voltage, such as photo detectors): a. Connect the guard ring to the non-inverting input pin (VIN+). This biases the guard ring to the same reference voltage as the op amp (e.g., VDD/2 or ground). b. Connect the inverting pin (VIN-) to the input with a wire that does not touch the PCB surface. Non-inverting Gain and Unity-Gain Buffer: a. Connect the non-inverting pin (VIN+) to the input with a wire that does not touch the PCB surface. b. Connect the guard ring to the inverting input pin (VIN-). This biases the guard ring to the common mode input voltage. DS21811C-page 12 R1 SW R C VOUT VIN + VDD/2 MCP6281 - VOUT 1 = sRC VIN FIGURE 3-9: Miller Integrator. 2004 Microchip Technology Inc. MCP6281/2/3/4/5 3.8.3 CASCADED OP AMPS APPLICATIONS R4 R3 The MCP6285 provides the flexibility of low power mode for dual op amps in an 8-pin package. The MCP6285 eliminates the added cost and space in battery-powered applications by using two single op amps with chip select lines or a 10-pin device with chip select line for each op amp. The only inherent limitation to this device is that the two op amps are internally cascaded. Therefore, this device cannot be used in circuits that require active or passive elements between the two op amps. However, there are several applications where this op amp configuration with chip select line becomes suitable. The circuits below show possible applications for this device. FIGURE 3-11: Configuration. 3.8.3.1 3.8.3.3 Load Isolation With the cascaded op amp configuration, op amp B can be used to isolate the load from op amp A. In applications where op amp A is driving capacitive or low resistance loads in the feedback loop (such as an integrater circuit or filter circuit) the op amp may not have sufficient source current to drive the load. In this case, op amp B can be used as a buffer. R2 B A VIN VOUTB CS Cascaded Gain Circuit Difference Amplifier Figure 3-12 shows op amp A configured as a difference amplifier with chip select. In this configuration, it is recommended to use well-matched resistors (0.1%) to increase the common mode rejection ratio (CMRR). Op amp B can be used to provide additional gain and isolate the load from the difference amplifier.

Cascaded Gain Figure 3-11 shows a cascaded gain circuit configuration with chip select. Op amps A and B are configured in a non-inverting amplifier configuration. In this configuration, it is important to note that the input offset voltage of op amp A is amplified by the gain of op amp A and B as shown below: V OUT = V IN G A G B + V OSA G A G B + V OSB G B Where: GA = op amp A gain GB = op amp B gain VOSA = op amp A offset voltage VOSB = op amp B offset voltage Therefore, it is recommended to set most of the gain with op amp A and use op amp B with relatively small gain, or as a unity-gain buffer. 2004 Microchip Technology Inc. DS21811C-page 13 MCP6281/2/3/4/5 3.8.3.4 Buffered Non-inverting Integrator Figure 3-13 shows a buffered non-inverting integrator with chip select. Op amp A is configured as a noninverting integrator. In this configuration, matching the impedance at each input is recommended. Rf is used to provide a feedback loop at frequencies << 1/(2RC). Op amp B is used to isolate the load from the integrator. R1 Second-Order MFB Low-Pass Filter with an Extra Pole-Zero Pair Figure 3-15 is a second-order multiple feedback lowpass filter with chip select.

The alternative is to use a passive element such as a resistor for compensation. However, the quality of compensation would not be constant since the AC characteristics of an amplifier varies over temperature and process. This circuit uses op amp B as a unity-gain buffer to isolate the integration capacitor C1 from op amp A and drives the capacitor with low impedance source. Since both amplifiers are matched very well, it provides higher quality of integration.

The op amp's GBWP sets the corner frequency. R1 and R2 are used to set the circuit gain and R3 is used to set the Q. To avoid gain peaking in the frequency response, Q needs to be low (lower values need to be selected for R3). Note that the amplifier bandwidth varies greatly over temperature and process. However, this configuration provides a lowcost solution for applications with high bandwidth.

Note the following details of the code protection feature on Microchip devices: * Microchip products meet the specification contained in their particular Microchip Data Sheet. * Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. * There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. * Microchip is willing to work with the customer who is concerned about the integrity of their code. * Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as "unbreakable." Code protection is constantly evolving.
