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.
