3 Description

The OPA551x devices are low-cost operational

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

The OPA551 is unity-gain stable and features high

slew rate (15 V/μs) and wide bandwidth (3 MHz). The

OPA552 is optimized for gains of 5 or greater, and

offers higher speed with a slew rate of 24 V/μs and a

bandwidth of 12 MHz. Both devices 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 OPA55x devices are internally protected against

overtemperature conditions and current overloads.

The thermal shutdown indicator flag provides a current output to alert the user when thermal

shutdown has occurred.

The OPA55x devices are available in PDIP-8 and SOIC-8 packages, as well as a DDPAK-7/TO-263

surface-mount plastic power package. They are

specified for operation over the extended industrial

temperature range, –40°C to +125°C.
