DC measurement with ADAU1961

JosefPeter on Oct 12, 2015

Hello,

The ADAU1961 was designed to convert audio signals, but we have a sensor where we have to measure a DC-Signal. Ist this also possible with the ADAU1961?

Thank you for your help!

One relatively simple way to do this would be to use some analog switches to chop the DC signal. You can then AC couple and feed the generated square wave to the ADC and compute the DC value from the peak…
