A High Speed, Three Op-Amp In-Amp
The circuit of Figure 26 lends itself well to CCD imaging and
other video speed applications. It uses two high speed CB pro-
cess op-amps: Amplifier A3, the output amplifier, is an AD847.

CIRCUIT GAIN =
The input amplifier (A1 and A2) is an AD827, which is a dual
version of the AD847. This circuit has the optional flexibility of
both dc and ac trims for common-mode rejection, plus the abil-
ity to adjust for minimum settling time.
