ear Dan, Thank you for your quick response.(Please visit the site to view this file) Please find the drive circut schematic. I am afraid I can not check if the schematic pdf file has uploaded properly. The ADC is driven by LHM6553 fully differential amplifier. The common mode voltage for LHM6553 is provided by ADS61B49 . I gave an input voltages for ADS61B49 exceeding full scale 2 Vpp(say 3Vpp) through the drive circuit of LTH6553 of which gain is 1. Data outputs of ADC is LVDS. The data was captured by our Zync based FPGA board and TI's capture board TSW1405. Kind Regards, K. Kobayashi
