FEATURES
DESCRIPTION
The OPA621 is a precision wideband monolithic opera-
tional amplifier featuring very fast settling time, low
differential gain and phase error, and high output
current drive capability.
The OPA621 is stable in gains of 2V/V or higher. This
amplifier has a very low offset, fully symmetrical
differential input due to its “classical” operational am-
plifier circuit architecture. Unlike “current-feedback”

APPLICATIONS
amplifier designs, the OPA621 may be used in all op
amp applications requiring high speed and precision.
Low noise and distortion, wide bandwidth, and high
linearity make this amplifier suitable for RF and video
applications. Short circuit protection is provided by an
internal current-limiting circuit.
The OPA621 is available in DIP and SO-8 packages.
