(Ta = 25°C; AVDD =2.2 ∼ 3.6V, DVDD =1.6 ∼ 3.6V, SVDD =2.2 ∼ 4.0V; fs=44.1kHz; DEM=OFF)
Note 23. The passband and stopband frequencies scale with fs (system sampling rate).
Note 24. The calculation delay time caused by digital filtering. This time is from the input of analog signal to setting of the

For example, ADC is PB = 20.0kHz = 0.454*fs (@-1.0dB). Each response refers to that of 1kHz.
16-bit data of both channels to the output register of the ADC. This time includes the group delay of the HPF. 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.
