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 (15Vs) and wide bandwidth (3MHz). The OPA552 is optimized for gains of 5 or greater, and offers higher speed with a slew rate of 24V/s 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 surfacemount plastic power package. They are specified for operation over the extended industrial temperature range, 40C to +125C.
