The OPA548T is a high-voltage and high-current Operational Amplifier, 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 OPA548T device operates from either single or dual supplies for design flexibility. In single-supply operation, the input common-mode range extends below ground. The OPA548T device is internally protected against over-temperature conditions and current overloads. In addition, the OPA548T device was designed to provide an accurate, user-selected current limit. Unlike other designs, which use a resistor in series with the output current path, the OPA548T device senses the load indirectly. This allows the current limit to be adjusted from 0 to 5A with a resistor and potentiometer or controlled digitally with a voltage-out or current-out DAC. The enable/status (E/S) pin provides two functions.
3A Continuous, 5A peak high-output current
Wide output voltage swing
Thermal shutdown and adjustable current limit protection
Output disable control
Thermal shutdown indicator
10V High slew rate
Low quiescent current
Green product and no Sb/Br
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
