Hello,
I run an ADS1292 with bipolar voltage and I use an external reference.
The data sheet says that the VREFN pin must always be connected to AVSS.
I have found that the actual reference voltage is the sum of AVSS and external Refenece.
Can I connect the VREFN pin to ground? If not, how can I operate the ADS1292 so that the reference voltage in the ADC corresponds to the external reference voltage?
Thanks in advance
