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 CS5501’s source impedance requirements. For more information refer the text section Analog Input Impedance Considerations. 2. Applies after calibration at the temperature of interest. 3. Total drift over the specified temperature range since calibration at power-up at 25 °C (see Figure 11). This is guaranteed by design and /or characterization. Recalibration at any temperature will remove these errors.
