OPA551

OPA552

High-Voltage, High-Current

OPERATIONAL AMPLIFIERS

DESCRIPTION

The OPA551 and OPA552 are low cost op amps with high-

voltage (60V) and high-current (200mA) capability.

The OPA551 is unity-gain stable and features high slew rate

(15V

µs) and wide bandwidth (3MHz). The OPA552 is

optimized for gains of 5 or greater, and offers higher speed

with a slew rate of 24V/

µs and a bandwidth of 12MHz. Both

are suitable for telephony, audio, servo, and test applications.

These laser-trimmed, monolithic integrated circuits provide

excellent low-level accuracy along with high output swing.

High performance is maintained as the amplifier swings to

its specified limits.

The OPA551 and OPA552 are internally protected against

over-temperature conditions and current overloads. The

thermal shutdown indicator “flag” provides a current output

to alert the user when thermal shutdown has occurred.

The OPA551 and OPA552 are available in DIP-8 and

SO-8 packages, as well as a DDPAK-7 surface-mount

plastic power package. They are specified for operation

over the extended industrial temperature range, –40

°C to

+125

°C.
