OPA564AQDWPRQ1

The OPA564-Q1 is a low-cost, high-current op-amp well suited for driving up to 1.5A into reactive loads. The high slew rate provides 1.3MHz full-power bandwidth and excellent linearity. These monolithic ICs deliver high reliability in demanding power line communication and motor control applications. The OPA564-Q1 operates from a single supply of 7V to 24V or dual supplies of ±3.5V to ±12V. In single-supply operation, the input common-mode range extends to the negative supply. At maximum output current, the wide output swing delivers 20VPP (IOUT = 1.5A) performance from a nominal 24V supply voltage. The OPA564-Q1 is protected internally against overtemperature conditions and current overload. The device provides accurate, user-selectable current limiting. Two flag outputs are provided: one indicates current limit and the other indicates overtemperature. The device also features an enable/shutdown (E/S) pin that can be forced low to disable the output, effectively disconnecting the load. The OPA564-Q1 is available in a thermally enhanced, surface-mount PowerPAD IC package (HSOIC-20).
