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.
