Hello,
Can someone suggest a suitable circuit for using PGA117 as a thermocouple amplifier. The input may go down to
-10mV. Will a bias on Vref pin and connecting the T/C between Vref and an input channel accomplish this (Do I need to,or can simply connect it between the channel and Gnd once Vref is biased .). Is it safe to connect Vref point to the TC cable from the noise perspective.
Regards
Nikhil
