OPA564数据手册TI中文资料规格书

描述 Description

The OPA564 is a low-cost, high-current operational amplifier that is ideal for driving up to 1.5A into reactive loads. The high slew rate provides 1.3MHz full-power bandwidth and excellent linearity. These monolithic integrated circuits provide high reliability in demanding powerline communications and motor control applications. The OPA564 operates from a single supply of 7V to 24V, or dual power supplies of ±3.5V to ±12V. In single-supply operation, the input common-mode range extends to the negative supply. At maximum output current, a wide output swing provides a 20VPP (IOUT = 1.5A) capability with a nominal 24V supply. The OPA564 is internally protected against over-temperature conditions and current overloads. It is designed to provide an accurate, user-selected current limit. Two flag outputs are provided; one indicates current limit and the second shows a thermal over-temperature condition. It also has an Enable/Shutdown pin that can be forced low to shut down the output, effectively disconnecting the load. The OPA564 is housed in a thermally-enhanced, surface-mount PowerPAD™ package (HSOP-20) with the choice of the thermal pad on either the top side or the bottom side of the package. Operation for both versions is specified over the industrial temperature range, –40°C to +85°C.
