Notes:
1. The AIN pin presents 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 CS5505/6/7/8’s source impedance requirements. For more information refer to the
text section Analog Input Impedance Considerations.
2. Specifications guaranteed by design, characterization and/or test.
3. Applies after calibration at the temperature of interest.
4. Total drift over the specified temperature range since calibration at power-up at 25°C.
Recalibration at any temperature will remove these errors.
