Hi Team,

Good day, we received inquiry from customer regarding ADS1261. For me to not miss any information, ill copy the query below.


1. in the datasheet of ADS1261, CMRR=115dB. I want to know the test conditions to have this value. How much common mode voltage was applied to inputs of the ADC?"

2. ADS1261 CMRR value was tested at which input common mode voltage: 5V or 2.5V?
