PA02 PA02A RoHS Power Operational Amplifiers COMPLIANT FEATURES High Power Bandwidth 350 kHz High Slew Rate 20V/s 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 APPLICATIONS Motor, Valve and Actuator Control Magnetic Deflection Circuits up to 5A Power Transducers up to 350 kHz Audio Amplifiers up to 30W RMS DESCRIPTION The PA02 and PA02A are wide-band, high output current operational amplifiers designed to drive resis- tive, inductive and capacitive loads. Their complementary collector output stage can swing close to the sup- ply 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 heat- sink of proper rating is recommended. These hybrid integrated circuits utilize thick film (cermet) resistors, ceramic capacitors and semiconduc- tor 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.
