OPA548 - Texas Instruments

OPA548 High-Current Operational Amplifier

The OPA548 device is a low-cost, high-voltage, and high-current operational amplifier that is designed to drive a wide variety of loads. A laser-trimmed, monolithic, integrated circuit provides excellent lowlevel signal accuracy and high-output voltage and current. The OPA548 operates from either single or dual supplies for design flexibility. In single-supp.
