tHello team,
My customer is only using ADC for this device. (No DAC)
They are observing DC offset drift of +/- 5mV for the ADC, and they are struggling to calibrate this offset, because it drift with time/temp.
They are calibrating by measuring the offset by shorting the input of ADC, and measure the output for 1min. They will take average of the output to cancel the DC offset.
Is there any way to cancel this DC offset drift?
Best Regards,
Kei Kuwahara
