DAC Digital Filter (LPF) + SCF:
Frequency Response: 0 ∼ 20.0kHz
Note 32. The passband and stopband frequencies scale with fs (system sampling rate).
Note 33. The calculated delay time caused by digital filtering. This time is from the input of analog signal to setting of the
MS0666-E-00
For example, DAC is PB=0.454 x fs (@−0.7dB). Each response refers to that of 1kHz.
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.
“ideal” code at 1.1V.
16-bit data of both channels from the input register to the output register of the ADC.
