Group Delay (Fs = Output Sample Rate) (Note 7)
Group Delay Variation vs. Frequency
4. Input resistance is for the input selected. Non-selected inputs have a very high (>1MΩ) input resistance.
5. Filter characteristics scale with output sample rate.
6. The analog modulator samples the input at 5.6448 MHz for an output sample rate of 44.1 kHz. There is
7. Group delay for Fs = 44.1 kHz, t
The input resistance will vary with gain value selected, but will always be greater than the min. value
specified
no rejection of input signals which are multiples of the sampling frequency (n × 5.6448 MHz ±20.0 kHz
where n = 0,1,2,3...).
