DESCRIPTION
The OMA541 is a power operational amplifier capable of operation from power
supplies up to 鹵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.
