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. This product includes three distinctively
different package styles. They are the industry standard TO-3, an enhanced TO-3
with a copper slug and the optimum style, a dual in-line power package. This device
is ideally suited for Military motor driver, servo amplifier, synchro exertation as well as
other power drive circuitry and approved to DESC drawing 5962-88701.
