The AD8138’s differential output helps balance the input to
differential ADCs, maximizing the performance of the ADC.The AD8138 eliminates the need for a transformer with high
performance ADCs, preserving the low frequency and dc infor-mation. The common-mode level of the differential output is
adjustable by a voltage on the V OCM pin, easily level-shifting the
input signals for driving single-supply ADCs. Fast overload
recovery preserves sampling accuracy.
