Differential-Output Difference Amplifier System with G = ½

High-performance ADCs typically run on low-voltage supplies. To process ±10 V or larger signals, an amplifier precedes the ADC, attenuating the signal to keep it from saturating or damaging the inputs. Differential outputs are desirable to capture the full benefits of the differential-input ADC, including increased dynamic range, improved common-mode rejection, and reduced noise sensitivity.
