Zusammenfassung:	The present disclosure relates generally to digital microphone and other sensor assemblies including a transducer, a delta-sigma analog-to-digital converter (ADC), a dynamic element matching (DELM) entity configured to compensate for nonlinearity resulting from variation among digital-to-analog conversion (DAC) elements of the ADC, and a control circuit configured to enable and disable the DELM based on a magnitude of a digital signal generated by the ADC.
