DESCRIPTION
The OPA620 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 OPA620 is internally compensated for unity-gain
stability. This amplifier has a very low offset, fully
symmetrical differential input due to its “classical”
operational amplifier circuit architecture. Unlike “cur-
rent-feedback” amplifier designs, the OPA620 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 OPA620 is available in plastic and ceramic DIP
and SO-8 packages. Two temperature ranges are of-
fered: –40°C to +85°C and –55°C to +125°C.
