Differential Output Instrumentation Amplifier
The addition of a third amplifier to the conventional three
amplifier Instrumentation Amplifier introduces the benefits of
differential signal realization, specifically the advantage of
using common mode rejection to remove coupled noise and
ground-potential errors inherent in remote transmission. This
configuration also provides enhanced bandwidth, wider
output swing and faster slew rate than conventional three
amplifier solutions with only the cost of an additional
amplifier and few resistors.
