These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the operational amplifer to go to the V+ voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was negative, again returns to a value greater than -0.36V (at 25C). Short circuits from the output V+ can cause excessive heating and eventual destruction. When considering short circuits to ground the maximum output current is approximately 40mA independent of the magnitude of V+. At values of supply voltage in excess of +15V, continuous short circuits can exceed the power dissipation ratings and cause eventual destruction. The maximum power dissipation is a function of TJ(MAX), JA , and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) - TA)/ JA. All numbers apply for packages soldered directly onto a PC board. 6.2 ESD Ratings V(ESD) (1) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001 (1) VALUE UNIT 300 V JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

This amplifier operates over a wide range of power supply voltages, with little change in performance characteristics. At 25C amplifier operation is possible down to a minimum supply voltage of 3 V. Large differential input voltages can be easily accommodated and, as input differential voltage protection diodes are not needed, no large input currents result from large differential input voltages. The differential input voltage may be larger than V+ without damaging the device. Protection should be provided to prevent the input voltages from going negative more than -0.3 VDC (at 25C). An input clamp diode with a resistor to the IC input terminal can be used. 7.2 Functional Block Diagram 7.3 Feature Description To reduce the power supply drain, the amplifier has a class A output stage for small signal levels which converts to class B in a large signal mode. This allows the amplifiers to both source and sinks large output currents. Therefore both NPN and PNP external current boost transistors can be used to extend the power capability of the basic amplifiers. The output voltage needs to raise approximately 1 diode drop above ground to bias the on chip vertical PNP transistor for output current sinking applications. For AC applications, where the load is capacitively coupled to the output of the amplifier, a resistor should be used, from the output of the amplifier to ground to increase the class A bias current and to reduce distortion. Capacitive loads which are applied directly to the output of the amplifier reduce the loop stability margin. Values of 50 pF can be accommodated using the worst-case non-inverting unity gain connection. Large closed loop gains or resistive isolation should be used if large load capacitance must be driven by the amplifier. The bias network of the LM321 establishes a supply current which is independent of the magnitude of the power supply voltage over the range of from 3 VDC to 30 VDC. Output short circuits either to ground or to the positive power supply should be of short time duration. Units can be destroyed, not as a result of the short circuit current causing metal fusing, but rather due to the large increase in IC chip dissipation which will cause eventual failure due to excessive junction temperatures. The larger value of output source current which is available at 25C provides a larger output current capability at elevated temperatures than a standard IC operational amplifer.

TI's customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information The LM321 operational amplifer can operate with a single or dual power supply voltage, has true-differential inputs, and remain in the linear mode with an input common-mode voltage of 0 VDC. This amplifier operates over a wide range of power supply voltages, with little change in performance characteristics. At 25C amplifier operation is possible down to a minimum supply voltage of 3 V.

Output short circuits either to ground or to the positive power supply should be of short time duration. Units can be destroyed, not as a result of the short circuit current causing metal fusing, but rather due to the large increase in IC chip dissipation which will cause eventual failure due to excessive junction temperatures. The larger value of output source current which is available at 25C provides a larger output current capability at elevated temperatures than a standard IC operational amplifer. The circuits presented in the section on typical applications emphasize operation on only a single power supply voltage. If complementary power supplies are available, all of the standard operational amplifer circuits can be used. In general, introducing a pseudo-ground (a bias voltage reference of V+/2) will allow operation above and below this value in single power supply systems. Many application circuits are shown which take advantage of the wide input common-mode voltage range which includes ground. In most cases, input biasing is not required and input voltages which range to ground can easily be accommodated.

The circuit gives an inverted output which is equal to the weighted algebraic sum of all four inputs. The gain of any input of this circuit is equal to the ratio of the appropriate input resistor to the feedback resistor. The advantage of this circuit is that there is no interaction between inputs and operations such as summing and weighted averaging are implemented very easily.

When the MOSFET is on, the circuit acts as an inverting amplifier with gain 1. When The MOSFET is off, the inverting and non-inverting signals cancel each other out.

Lamp Driver Schematic 9 Power Supply Recommendations The LM321 is specified for operation up to 32 V; many specifications apply from -40C to 85C. Parameters that can exhibit significant variance with regard to operating voltage or temperature are presented in Typical Characteristics. Place 0.1-F bypass capacitors close to the power-supply terminals to reduce errors coupling in from noisy or high-impedance power supplies. For more detailed information on bypass capacitor placement, see Layout. 10 Layout 10.1 Layout Guidelines For best operational performance of the device, use good printed circuit board (PCB) layout practices, including: * Noise can propagate into analog circuitry through the power pins of the circuit as a whole and operational amplifer itself. Bypass capacitors are used to reduce the coupled noise by providing low-impedance power sources local to the analog circuitry. - Connect low-ESR, 0.1-F ceramic bypass capacitors between each supply pin and ground, placed as close to the device as possible. A single bypass capacitor from V+ to ground is applicable for single supply applications. * Separate grounding for analog and digital portions of circuitry is one of the simplest and most-effective methods of noise suppression. One or more layers on multilayer PCBs are usually devoted to ground planes. A ground plane helps distribute heat and reduces EMI noise pickup. Make sure to physically separate digital and analog grounds paying attention to the flow of the ground current. For more detailed information refer to Circuit Board Layout Techniques, SLOA089. * In order to reduce parasitic coupling, run the input traces as far away from the supply or output traces as possible. If it is not possible to keep them separate, it is much better to cross the sensitive trace perpendicular as opposed to in parallel with the noisy trace. * Place the external components as close to the device as possible. As shown in Figure 15, keeping RF and RG close to the inverting input minimizes parasitic capacitance. * Keep the length of input traces as short as possible. Always remember that the input traces are the most sensitive part of the circuit. * Consider a driven, low-impedance guard ring around the critical traces. A guard ring can significantly reduce leakage currents from nearby traces that are at different potentials.
