Texas Instruments OPA549

the opa549 is a low-cost high-voltage/high-current operational amplifier ideal for driving a wide variety of loads. this laser-trimmed monolithic integrated circuit provides excellent low-level signal accuracy and high output voltage and current. the opa549 operates from either single or dual supplies for design flexibility. the input common-mode range extends below the negative supply. the opa549 is internally protected against over-temperature conditions and current overloads. in addition the opa549 provides an accurate user-selected current limit. unlike other designs which use a "power" resistor in series with the output current path the opa549 senses the load indirectly. this allows the current limit to be adjusted from 0a to 10a with a resistor/potentiometer or controlled digitally with a voltage-out or current-out digital-to-analog converter (dac). view all in datasheet
