PDS-1472A

Printed in U.S.A. July, 1999

High-Voltage, High-Current

OPERATIONAL AMPLIFIERS

DESCRIPTION

The OPA551 and OPA552 are low cost op amps with

high-voltage (60V) and high-current (200mA) capa-

bility.

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 over-

loads. The thermal shutdown indicator “flag” provides

a current output to alert the user when thermal shut-

down 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.
