ADAU1701 accuracy of DAC full-scale-analog-output

Question asked by Thomas.DE on Nov 20, 2013

Hello there,


The ADAU1701's datasheet tells me, that the full scale analog DAC output is 0,9 VRMS, but I measure 1 VRMS.

(The DAC output feeds an active filter in my application.)


This results in an accuracy of 11%, which is more than the gainerror given by the datasheet.


How is the absolute accuracy of the dac full scale analog output with a high impedance as load, e.g. 10 kOhm ?


Best regards
