The PA02 and PA02A are wideband, high output current operational amplifiers designed to drive resistive, inductive and capacitive loads. Their complementary "collector output"stage can swing close to the supply 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 heatsink of proper rating is recommended.
These hybrid integrated circuits utilize thick film (cermet)resistors, ceramic capacitors and semiconductor chips to maximize reliability, minimize size and give top performance.Ultrasonically bonded aluminum wires provide reliable inter-connections at all operating temperatures. The 8-pin TO-3package is hermetically sealed and electrically isolated.Isolation washers are not recommended. The use of com-pressible thermal washers and/or improper mounting torque will void the product warranty. Please see "General Operating Considerations".
