DESCRIPTION
The OPA651 is a low power, wideband voltage feed-
back operational amplifier. It features a bandwidth at
G = +2 of 470MHz as well as a 12-bit settling time of
only 16ns. The wide bandwidth and true differential
input stage make it suitable for use in a variety of
applications. Its low distortion gives exceptional per-
formance for telecommunications, medical imaging
and video applications.
The OPA651 is compensated for stability in gains of
two or more, differentiating it from the unity gain
stable OPA650. Its unusual combination of speed,
accuracy and low power make it an outstanding choice
for many portable, multi-channel and other high speed
applications, where power is at a premium.
