AD588
Additional common-mode voltage reduction is realized by using
the circuit illustrated in Figure 28. A1, the ground sense ampli-
fier, serves the supplies on the bridge to maintain a virtual ground
at one center tap. The voltage that appears on the opposite
center tap is now single-ended (referenced to ground) and can
be amplified by a less expensive circuit.
