I am having so much of trouble confusing between reference electrode and bias electrode Please help me out.
1) By referring 'INM' which pin do you mean? Is it same as INPN?
2) For each channel, there are 4 pins, INPP, INPN, and two other pins which are shorted together to pin 1 at JP25. What is the significacne of pin 1 of JP25. I believe it is neither the ground nor the reference pin. Is it right to say we can short INPxN to the reference pins via registers? If so what is the need of 4 pin per channel?
3) Is it correct to route Bias_elect to the bias pin of ads1299, rather than biasing our body to mid supply voltage? If so should we configure JP1
4) What is Bias_DRV? how to connect, where to connect?
With regards
