Internal CURRENT limitcircuitry can be user-programmed with a single external resistor, protecting theamplifier and load from fault conditions.

2 The OMA541 pinout is compatible withpopular power OPERATIONAL amplifiers such as the OPA511, OPA512 and device is ideally suited for Military motor driver, servo amplifier, synchroexertation as well as other power drive circuitry.
