Description

The PA51 and PA51A are high voltage, high output current operational amplifiers designed to drive resistive, inductive and capacitive loads. Their complementary common emitter output stage of PA51 is the simple class C type optimized for low frequency applications where crossover distortion is not critical. These amplifiers are not recommended for audio, transducer or deflection coil drive circuits. The safe operating area (SOA) PA51 is fully specified and can be observed for all operating conditions by selection of user programmable current limiting resistors. Both amplifiers are internally compensated for all gain settings. For continuous operation under load, mounting on a heatsink of proper rating is recommended. Do not use isolation washers!

This hybrid integrated circuit utilizes thick film conductors PA51, ceramic capacitors and semiconductor chips to maximize reliability, minimize size and give top performance. Ultrasonically bonded aluminum wires of PA51  provide reliable interconnections at all operating temperatures. The 8-pin TO-3 package of PA51 is electrically isolated and hermetically sealed. The use of compressible thermal washers and/or improper mounting torque will void the product warranty. Please see Application Note 1 "General Operating Considerations,"

The PA51A is the A grade version, the PA51M/883 is the certified military grade version.

Applications:

• DC Servo Amplifier
• Motor/Synchro Driver
• Valve and Actuator Control
• DC or AC Power Regulator
