Overview
The OPA564AIDWD is a high-current operational amplifier produced by Texas Instruments. It is designed to drive up to 1.5A into reactive loads, making it ideal for applications requiring high output current and wide power-supply ranges. The amplifier features a high slew rate, providing a full-power bandwidth of 1.3MHz and excellent linearity. It operates from a single supply of +7V to +24V or dual power supplies of ±3.5V to ±12V, and is housed in a thermally-enhanced, surface-mount PowerPAD™ package (HSOP-20) with the thermal pad on either the top or bottom side of the package.
