Notes:
22. Response is clock-dependent and will scale with F
23. For Single-Speed Mode, the measurement bandwidth is 0.5465 F
For Double-Speed Mode, the measurement bandwidth is 0.577 F
24. The DAC group delay is measured from the FS/LRCK transition (rising or falling) before the first bit of
a (group of) sample(s) is transmitted on the SDINx pins to the time it appears on the AOUTx pins.
