SBOS372C –OCTOBER 2008–REVISED NOVEMBER 2009

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 20V (I

= 1.5A) capability with a nominal 24V supply.

OUT

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

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, and in an HTSSOP-20 package with thermal pad on the bottom. Operation for all versions is specified over the industrial temperature range, –40°C to +85°C.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may

degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not supported.

(2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.4V beyond the supply rails should

be current limited to 10mA or less.

(3) Output terminals are diode-clamped to the power-supply rails. Input signals forcing the output terminal more than 0.4V beyond the

supply rails should be current limited to 10mA or less.

(4) Short-circuit to ground within SOA. See Power Dissipation and Safe Operating Area for more information.
