I'd like to know CMRR minimum value for AD1938.
Temperature condition is at 25 degrees Celsius and from -40 to +105 degrees Celsius.
I cannot found any minimum value in the data sheet.
If you cannot present it please let me know.
I was able to find the minimum CMRR specification at case temperatures of 25C and at 125C. In both cases the minimum CMRR was 46.5dB. This was with a 100mV input signal at 1kHz. I did not find the specification for -40C. It would take a lot more effort and involve some other engineers. Contact me directly if you need the data so I can ask you other questions.
Thanks for your reply.
If possible, please let me know.
Thanks and Regards,
