OPA567 轨至轨 I/O 2A 功率放大器
The OPA567 is a low-cost, high-current, operational amplifier designed for driving a wide variety of loads while operating on low-voltage supplies. It operates from either single or dual supplies for design flexibility and has rail-to-rail swing on the input and output. Output swing is within 300mV of the supply rails, with output current of 2A. Smaller loads allow an output swing closer to the rails.
The OPA567 is unity gain stable, easy to use, and free from the phase inversion problems found in some power amplifiers. High performance is maintained at voltage swings near the output rails.
The OPA567 provides an accurate user-selected current limit set with an external resistor, or digitally adjusted via a Digital-to-Analog Converter (DAC).
