Hi,

 

For Our upcoming project, requirement is to measure from 50nV to 1V. Previously, I worked with AD7124 to measure RTD,K-type thermocouple and Pressure sensor. Even if I get 100% throughput (All 24 bits) which is not practically possible, I will only get 150nV per count for 2.5V reference. So, I have to go to 32 bit ADC to get the accuracy. And also, we are thinking of selecting Adaptive gain ADC. Can anybody suggest suitable ADC?

 

 

 

Thanks,

Muthu
