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
(15Vµs) 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.
