OPA548 Low Frequency Power Operational Amplifier Module Current Amplifier 3A Continuous Current Wide Output Voltage Swing -79424

The OPA548 device is a low-cost, high-voltage and high-current operational amplifier that's ideal for driving a wide variety of loads. A laser-trimmed monolithic integrated circuit provides excellent low-level signal accuracy and high-output voltage and current.

The OPA548 device operates from either single or dual supplies for design flexibility. In single-supply operation, the input common-mode range extends below ground.

The OPA548 device is internally protected against over-temperature conditions and current overloads. In addition, the OPA548 device was designed to provide an accurate, user-selected current limit. Unlike other designs, which use a power resistor in series with the output current path, the OPA548 device senses the load indirectly. This allows the current limit to be adjusted from 0 A to 5 A with a resistor and potentiometer or controlled digitally with a voltage-out or current-out DAC.
