Hi,

I am working on differential Multi-channel high precision DAS. I have chosen the following architectures.

Spec: CMRR -  >=50dB @ 0 to 1Khz

         Gain Error - 0.02%

Architecture 1:

AAF --> MUX --> IA --> Post amplifiers --> ADC

But…

Hi,

I am designing a multi-channel DAS. The specificatios or as given below;

Total channels : 24

Analog input signal range : +/- 10V

Resolution of ADC : 16 bit

Gain error : <= 0.02% of FSR i.e <=4mV

Offset voltage : +/-1.2mV

Temperature…
