When input of AD4134 is±2V,output data is 0.test data is below:
Please help to check why output is 0 when ADC input is ±2V. Is SCH hardware or software maybe problem?thanks.

Hi dapan0518 ,
Can you please help share the table in excel file and the register settings as well?
Is the 2nd column the differential input ( AIN+ - AIN-) to the ADC? The output code is twice of what I calculated. For 1V input, I would expect code close to ~2048000
Output code = 1V*(2^24)/(2*4.096) = 2048000
Thanks,
Janine
Hello JEstayo,
The problem of AD4134 has been resolved,read of output data was wrong,now it's ok.thanks for your reply.
