Motors & Drives Information

Operating from single or dual supplies, Model OPA567 has rail-to-rail swing on input and output. Output swing is within 300 mV of supply rails with output current of 2 A. Diagnostic flag is provided for temperature overstress and can be configured to provide thermal shutdown. Housed in 5 x 5 mm QFN package, op amp is suited for driving valves, actuators, laser diode pumps, and servo motors, as well as thermoelectric coolers and synchro drivers.

Dallas, TX - Texas Instruments Incorporated (NYSE: TXN) introduced a high-current, low-cost power operational amplifier (op amp) designed for driving a wide variety of loads while operating on low- voltage supplies. The easy-to-use OPA567, from the company's Burr-Brown product line, operates from either single or dual supplies for design flexibility and can be used in virtually any op amp configuration.

This unity gain stable device has rail-to-rail swing on the input and output. The output swing is within 300mV of the supply rails with output current of 2A. Lower-current loads allow an output swing closer to the rails resulting in higher performance. The op amp is ideal for driving valves, actuators, laser diode pumps and servo motors. Other applications include thermoelectric coolers, synchro drivers and transducer excitation. The OPA567 can be integrated with a 12-bit A/D and D/A component such as the AMC7823 or a standalone 12-bit D/A converter such as the DAC7551. An additional feature of the OPA567 is a diagnostic flag for temperature overstress. The temperature flag can also be configured to provide thermal shutdown.
