DESCRIPTION
The OMA512 is a high voltage, very high current operational amplifier designed to
drive a wide variety of resistive and reactive loads. The circuit is a hybrid integrated
type housed in a variety of hermetically sealed packages and is isolated from the
case. It is ideally suited for critical environments in applications such as motor
drivers, servo amplifiers, audio amplifiers and synchro exertation.
