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.
