The OPA564 is a low-cost, high-current operational amplifier that is ideal for driving up to 1.5A into reactive loads. It features high gain-bandwidth product, large output swing, fast response, and complete protection.
The OPA564 is a low‑cost, high‑current operational amplifier that can drive up to 1.5 A into reactive loads. It operates from a single supply of 7 V to 24 V (or dual ±3.5 V to ±12 V), offers a 20 Vpp output swing, and includes built‑in thermal shutdown and adjustable current‑limit protection with diagnostic flags.
The device is offered in HSOP‑20 (PowerPAD top or bottom) and HTSSOP‑20 packages. Detailed electrical characteristics include a 17 MHz gain‑bandwidth product, 40 V/µs slew rate, and typical input offset voltage of 10 mV. Pin descriptions and functional diagrams cover enable/shutdown control, current‑limit flag, and temperature‑sense pins, supporting applications such as motor drivers, audio power amplifiers, and power‑line communications.
