PA07A - FET Input Power Operational Amplifier, 100V, 5A, "A" grade
The PA07A is a high voltage, high output current operational amplifier designed to drive resistive, inductive and capacitive loads. For optimum linearity, especially at low levels, the output
stage is biased for class A/B operation using a thermistor compensated base-emitter voltage multiplier circuit. A thermal shutoff circuit protects against overheating and minimizes heatsink requirements for abnormal operating conditions. The safe operating area (SOA) 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, a heatsink of proper rating is recommended.
This hybrid circuit utilizes 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. The use of compressible washers
and/or improper mounting torque will void the product warranty.
