Product Summary
The OPA549S is a power operational amplifier capable of operation from power supplies up to ±40V and delivering continuous output currents 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 OPA549S is fabricated using a proprietary bipolar/FET process. Its applications include motor driver, servo amplifier, synchro excitation, audio amplifier and programmable power supply.
