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 is the simple class C type optimized for low frequency applications where crossover distortion is not critical.  PA51A are not recommended for audio, transducer or deflection coil drive circuits. The safe operating area (SOA) PA51A is fully specified and can be observed for all operating conditions by selection of user programmable current limiting resistors. Both amplifiers of PA51A 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 PA51A, 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 of PA51A is electrically isolated and hermetically sealed. The use of compressible thermal washers and/or improper mounting torque will void the product warranty. Please see "General Operating Considerations".
