We are planning to use the ADS7254 in a design that will sample one differential signal and one single ended signal. Would we be able to attach the minus input to GND of the single ended signal? The exact inputs are listed below.
AVDD=5V
REFIN_A= 3V
AINM_A=GND
AINP_A= 0-3V
Looking at the data sheet, it seems like this would be on the line for Vcm in the the +- Vref range. Am I able to extrapolate the Vcm using the two ranges listed on the datasheet?
Thanks,
