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.
