Description

The PA12 is a state of the art high voltage, very high output current operational amplifier designed to drive resistive, inductive and capacitive loads. For optimum linearity, especially at low levels, the output stage of PA12A is biased for class A/B operation using a thermistor compensated base-emitter voltage multiplier circuit.

The safe operating area (SOA) PA12A can be observed for all operating conditions by selection of user programmable current limiting resistors. For continuous operation under load, a heatsink of proper rating is recommended. This hybrid integrated circuit utilizes thick film (cermet)  resistors, ceramic capacitors of PA12A 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. The use of compressible isolation washers of PA12A voids the warranty.
