DIFFERENTIAL LINE RECEIVER
The differential receiver circuit of Figure 9 is useful for many
applications—from audio to video. It allows extraction of a low
level signal in the presence of common-mode noise, as shown in
Figure 10.

A HIGH SPEED, 3-OP AMP IN AMP
The circuit of Figure 11 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.
