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-supply operation, the input common-mode range extends below ground. The OPA548 is internally protected against overtemperature conditions and current overloads. In addition, the OPA548 is designed to provide an accurate, ...
