What is the possible cause of unexpected DC component at output of ADS5400?
Level of DC component is differ from device to device and reaches +2000 (decimal) (in two's complement mode) so it can't be compensated by Analog Offset Control register. (Some devices have no DC)
Signal goes to ADS5400 input through transformer and AC coupling capacitors so DC can't get outside into adc.
Supply voltages levels are within datasheet requirements.
Thanks in advance!
