Product Summary

The PA51A is a high voltage, high output current operational amplifier designed to drive resistive, inductive and capacitive loads. Its complementary common emitter output stage is the simple class C type optimized for low frequency applications where crossover distortion is not critical. The PA51A is not recommended for audio, transducer or defiection coil drive circuits. The applications of the PA51A are (1)DC servo amplifier; (2)motor/synchro driver; (3)valve and actuator control; (4)DC or AC power regulator.

Parametrics

PA51A absolute maximum ratings: (1)supply voltage, +VS to –VS: 80V; (2)output current, within SOA: 10A; (3)power dissipation, internal: 97W; (4)input voltage, differential: ±VS –3V; (5)input voltage, common mode: ±VS; (6)temperature, junction1: 200℃; (7)temperature, pin solder -10s: 300℃; (8)temperature range, storage:–65 to +150℃; (9)operating temperature range, case:–55 to +125℃.

Features

PA51A features: (1)wide supply range: ±10 to ±40V; (2)high output current: ±10A Peak; (3)class c output: Low Cost; (4)low quiescent current: 2.6mA.
