hi cypress,
I want to know that when low level sensor(uV level, like a strain gauge) input to PGA and ampilfier, then ADC 20bit selection. how much ADC output data has effect the ENOB, SNR etc...?
I know that 20Bit ADC's ENOB is about 18bit. but I think PGA will effect the ENOB on the total system.
blow is my schematic. please check it. thanks
