Currently am using AD8352 AC coupled differential amplifier to drive ADC AD9445, It is working fine for sine wave input with any frequency... The problem is whenever we try to apply a pulse input with varied duty cycle to differential amplifier it introduces an undesired DC OFFSET at the output....... what modification shall i make to work amplifier properly ( provides the clean output except DC OFFSET) with an varied duty cycle.... Am attaching the schematic....any help would be appreciated.....
