AD818

A HIGH SPEED, THREE OP AMP IN AMP

The circuit of Figure 41 uses three high speed op amps: two

AD818s and an AD817. This high speed circuit lends itself well

to CCD imaging and other video speed applications. It has the

optional flexibility of both dc and ac trims for common-mode

rejection, plus the ability to adjust for minimum settling time.
