Note: 7. The passband and stopband frequencies scale with fs.
For example, 21.8kHz at –0.1dB is 0.454 x fs (DAC). The reference frequency of these responses is 1kHz.
Note: 8. The calculating delay time occurred at digital filtering. This time is from setting the input of analog s signal to
setting the 24bit data of both channels to the output register of PORTB.
For DAC, this time is from setting the 20/24bit data of both channels on input register of PORTA to the
output of analog signal.
Note: 9. 40.0kHz@fs=96kHz, 80.0kHz@fs=192kHz.
