DESCRIPTION

The OMA541 is a power operational amplifier capable of operation from power

supplies up to ±40V and continuous output current up to 5A. Internal current limit

circuitry can be user-programmed with a single external resistor, protecting the

amplifier and load from fault conditions. The OMA541 pinout is compatible with

popular power operational amplifiers such as the OPA511, OPA512 and OPA3573.

This device is ideally suited for Military motor driver, servo amplifier, synchro

exertation as well as other power drive circuitry. The OMA541SKC incorporates a

copper slug to the header for improved thermal performance.
