Overview
The OPA564AIDWPR, produced by Texas Instruments, is a low-cost, high-current operational amplifier designed for driving up to 1.5A into reactive loads. This monolithic integrated circuit is ideal for demanding applications such as powerline communications and motor control due to its high reliability and robust features. The OPA564 operates from a single supply of 7V to 24V or dual power supplies of ±3.5V to ±12V, offering a wide output swing of 20VPP at 1.5A. It features a high slew rate, providing 1.3MHz full-power bandwidth and excellent linearity.
