Automotive 1.5A, 24V, 17MHz, Power Operational Amplifier

The OPA564-Q1

is a low-cost, high-current op amp that is an excellent choice for driving up to

1.5A into reactive loads. The high slew rate provides 1.3MHz of full-power bandwidth

and excellent linearity. These monolithic integrated circuits provide high

reliability in demanding powerline-communications and motor-control

applications.

The OPA564-Q1 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-Q1 is internally protected

against overtemperature conditions and current overloads. This device provides an

accurate, user-selected current limit. Two flag outputs are provided: one indicates

current limit and the other shows a thermal overtemperature condition. The device

also has an enable and shutdown (E/S) pin

that can be forced low to shut down the output, effectively disconnecting the

load.

The OPA564-Q1 is housed in a thermally

enhanced, surface-mount PowerPAD integrated circuit package (HSOIC-20).
