Power operational amplifiers from Texas Instruments with high current outputs suitable for driving low impedance and difficult loads. Many of these devices are capable of operating at higher supply voltages than general purpose op amps. Typical applications include driving MOSFETs and power transistors, bridge amplifiers, motor speed controllers, servo amplifiers, power supplies and uses within instrument systems.

The Texas Instruments OPA548 series devices are low-cost, high-voltage, and high-current operational amplifier that which are designed to drive a wide variety of loads. A laser-trimmed, monolithic, integrated circuit provides excellent low-level signal accuracy and high-output voltage and current.
