Accuracy (
Note 31
)
Note 31. Accuracy is the difference between the output code when 1.1V is input to SAIN1, SAIN2 or SAIN3 pin and the
“ideal” code at 1.1V.

Note 32. The passband and stopband frequencies scale with fs (system sampling rate).
For example, DAC is PB=0.454 x fs (@
0.7dB). Each response refers to that of 1kHz.
Note 33. The calculated delay time caused by digital filtering. This time is from the input of analog signal to setting of the
16-bit data of both channels from the input register to the output register of the ADC.
For the DAC, this time is from setting the 16-bit data of both channels from the input register to the output of
analog signal.
