In the datasheet of ADS1278 only the typical value of VCOM is mentioned. Can you please specify the minimum and maximum value for that.

    To help answer your question, please use the specs for the Absolute Input Voltage in the datasheet.  This is the VCM + Vdifsignal on the AINP or AINN pin.

    For general guidance, VCM should be limited to 1V-4V to allow room for your input signal, but this is NOT a min/max guarantee/spec.
