OPA569 2A 输出电流时输出信号摆幅在 200mV 轨之内的功率运算放大器
The OPA569 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. Typical output swing is within 150mV of the supply rails, with output current of 2A. Output swing closer to the rails is achievable with lighter loads.
The OPA569 is unity gain stable, has low dc errors, is 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 OPA569 provides an accurate user-selected current limit that is set with an external resistor, or digitally adjusted via a Digital-to-Analog Converter
