Product Details
High Voltage & High Current Op Amps
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 OPA551x devices are low-cost operational amplifiers with high-voltage (60-V) and high-current (200-mA) capability. The OPA551 is unity-gain stable and features high slew rate (15 V/μs) and wide bandwidth (3 MHz). The OPA552 is optimized for gains of 5 or greater, and offers higher speed with a slew rate of 24 V/μs and a bandwidth of 12 MHz. Both devices are suitable for telephony, audio, servo, and test applications.
