AK5394A Datasheet, PDF (9/24 Pages) Asahi Kasei Microsystems – Super High Performance 192kHz 24-Bit ADC

ASAHI KASEI
[AK5394A]
Notes: 7. The passband and stopband frequencies are proportional to fs.
8. The analog modulator samples the input at 6.144MHz for an output word rate of 48kHz.
There is no rejection of input signals which are multiples of the sampling frequency
(that is: there is no rejection for n x 6.144MHz ± 21.768kHz, where n=1,2,3···).
9. The calculating delay time which takes place due to the digital filtering process. This time is taken from when
the analog signal ia input, to the time of setting the 24-bit data (from both channels) to the output register.
65/fs typ. (normal/double/quad speed mode) at HPF=ON.
10. The analog modulator samples the input at 6.144MHz for an output word rate of 96kHz.
There is no rejection of input signals which are multiples of the sampling frequency
(that is: there is no rejection for n x 6.144MHz ± 43.536kHz, where n=1,2,3···)
11. The analog modulator samples the input at 6.144MHz for an output word rate of 192kHz.
There is no rejection of input signals which are multiples of the sampling frequency
(that is: there is no rejection for n x 6.144MHz ± 87.072kHz, where n=1,2,3···).
