FEATURES
• HIGH POWER BANDWIDTH — 350kHz • HIGH SLEW RATE — 20V/µs • FAST SETTLING TIME — 600ns • LOW CROSSOVER DISTORTION — Class A/B • LOW INTERNAL LOSSES — 1.2V at 2A • HIGH OUTPUT CURRENT — ±5A PEAK • LOW INPUT BIAS CURRENT — FET Input • ISOLATED CASE — 300 VDC

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.

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 protec-

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”.
