Notes:
1. The AIN and VREF pins present a very high input resistance at dc and a minor dynamic load which
scales to the master clock frequency. Both source resistance and shunt capacitance are therefore
critical in determining the source impedance requirements of the CS5516 and CS5520 at these pins.
2. Applies after system calibration at the temperature of interest.
