DESCRIPTION
The PA02 and PA02A are wideband, high output current operational amplifiers designed to drive resistive, inductive and capacitive loads. Their complementary "collector output" stage can swing close to the supply rails and is protected against inductive kickback. For optimum linearity, the output stage is biased for class A/B operation. The safe operating area (SOA) can be observed for all operating conditions by selection of user programmable, current limiting resistors (down to 10mA). Both amplifiers are internally compensated but are not recommended for use as unity gain followers. For continuous operation under load, mounting on a heatsink of proper rating is recommended. These hybrid integrated circuits utilize thick film (cermet) resistors, ceramic capacitors and semiconductor chips to maximize reliability, minimize size and give top performance. Ultrasonically bonded aluminum wires provide reliable interconnections at all operating temperatures. The 8-pin TO-3 package is hermetically sealed and electrically isolated. Isolation washers are not recommended. The use of compressible thermal washers and/or improper mounting torque will void the product warranty. Please see "General Operating Considerations".
LOW INTERNAL LOSS MAXIMIZES EFFICIENCY
When system voltages are low and power is at a premium, the PA02 is a natural choice. The circuit above utilizes not only the feature of low internal loss of the PA02, but also its very low distortion level to implement a crystal clear audio amplifier suitable even for airborne applications. This circuit uses AC coupling of both the input signal and the gain circuit to render DC voltage across the speaker insignificant. The resistor and capacitor across the inputs form a stability enhancement network. The 0.27 ohm current limit resistors provide protection in the event of an output short circuit.

The specification of PA02A is identical to the specification for PA02 in applicable column to the left. Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation to achieve high MTTF. The power supply voltage for all specifications is the TYP rating unless otherwise noted as a test condition. +VS and VS denote the positive and negative supply rail respectively. Total VS is measured from +VS to VS. Rating applies if the output current alternates between both output transistors at a rate faster than 60Hz. Exceeding CMV range can cause the output to latch. Full temperature specifications are guaranteed but not 100% tested. The internal substrate contains beryllia (BeO). Do not break the seal. If accidentally broken, do not crush, machine, or subject to temperatures in excess of 850°C to avoid generating toxic fumes.
