NEGATIVE OUTPUT OVERLOAD RESPONSE TIME Applications Information V+ Functional Description The ISL28177 is a low noise op amp fabricated in a 40V complementary bipolar DI process designed for general purpose low power applications. It utilizes a super-beta NPN input stage with input bias current cancellation for low input bias current and low input noise voltage. A complimentary bipolar output stage enables high capacitive load drive without external compensation. Operating Voltage Range The ISL28177 is designed to operate over the 6V (3V) to 40V (20V) range. The common mode input voltage range extends to 2V from each rail, and the output voltage swings to 1.3V of each rail. Input Performance The super-beta NPN input pair reduces input bias current while maintaining good frequency response, low input bias current and low noise. Input bias cancellation circuits provide additional bias current reduction to <1nA, and excellent temperature stabilization and low TCVOS. Input ESD Diode Protection The input terminals (IN+ and IN-) have internal ESD protection diodes to the positive and negative supply rails, series connected 500 current limiting resistors and an anti-parallel diode pair across the inputs (Figure 21). - 500 VIN + 500 VOUT RL V- FIGURE 21. INPUT ESD DIODE CURRENT LIMITING The series resistors limit the high feed-through currents that can occur in pulse applications when the input dv/dt exceeds the 0.2V/s slew rate of the amplifier. Without the series resistors, the input can forward-bias the anti-parallel diodes causing current to flow to the output, resulting in severe distortion and possible diode failure. Figure 17 provides an example of distortion free large signal response using a 10VP-P input pulse with an input rise time of <1ns. The series resistors enable the input differential voltage to be equal to the maximum power supply voltage (40V) without damage. In applications where one or both amplifier input terminals are at risk of exposure to high voltages beyond the power supply rails, current limiting resistors may be needed at the input terminal to limit the current through the power supply ESD diodes to 20mA max. Output Current Limiting The output current is internally limited to approximately 30mA at +25C and can withstand a short circuit to either rail as long as the power dissipation limits are not exceeded. Continuous operation under these conditions may degrade long term reliability. Output Phase Reversal Output phase reversal is a change of polarity in the amplifier transfer function when the input voltage exceeds the supply voltage. The ISL28177 is immune to output phase reversal. FN7859 Rev 2.00 April 5, 2012 Page 7 of 15 ISL28177 Power Dissipation ISL28177 SPICE Model It is possible to exceed the +150C maximum junction temperature under certain load and power supply conditions. It is therefore important to calculate the maximum junction temperature (TJMAX) for all applications to determine if power supply voltages, load conditions, or package type need to be modified to remain in the safe operating area. These parameters are related using Equation 1: Figure 22 shows the SPICE model schematic and Figure 23 shows the net list for the SPICE model. The model is a simplified version of the actual device and simulates important AC and DC parameters. AC parameters incorporated into the model are: 1/f and flatband noise voltage, Slew Rate, CMRR, Gain and Phase. The DC parameters are, VOS, IOS, total supply current and output voltage swing. The model uses typical parameters given in the "Electrical Specifications" table beginning on page 3. The AVOL is adjusted for 140dB with the dominant pole at 0.075Hz. The CMRR is set 145dB, fcm = 500kHz. The input stage models the actual device to present an accurate AC representation. The model is configured for ambient temperature of +25C. (EQ. 1) T JMAX = T MAX + JA xPD MAXTOTAL where: * PDMAXTOTAL is the sum of the maximum power dissipation of each amplifier in the package (PDMAX) * PDMAX for each amplifier can be calculated using Equation 2: V OUTMAX PD MAX = V S I qMAX + V S - V OUTMAX ---------------------------R (EQ. 2) L where: * TMAX = Maximum ambient temperature * JA = Thermal resistance of the package * PDMAX = Maximum power dissipation of 1 amplifier * VS = Total supply voltage * IqMAX = Maximum quiescent supply current of 1 amplifier * VOUTMAX = Maximum output voltage swing of the application Figures 24 through 37 show the characterization vs simulation results for the Noise Voltage, Closed Loop Gain vs Frequency, Small Signal 0.1V Step, Large Signal 5V Step Response, Open Loop Gain Phase, CMRR, Unity Gain Frequency Response vs CL and Output Voltage Swing for 15V supplies.
