Hello ,


Please Help me in understanding the effect of DC-Crosstalk on the accuracy of DAC. ?
As per Defination DC-Crosstalk of DAC is measured as follows :-
Setting DAC A to midscale ,
DAC B to zero .

And now keep monitoring DAC A output ( Which is fixed to mid level ) while changing DAC B to full scale .
Repeat same and maximum change recorded on DAC A will be the DC-Crosstalk.

Is error introduced by DC-Crosstalk calculated as % of ( Max Change in output of DAC A )/Original initial output of DAC A ) ?

Regards !!
