The AIN pin presents a very high input resistance at dc and a minor dynamic load which scales to the master clock frequency. Both sour ce 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 Consi derations. 2. Specifications guaranteed by desi gn, 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. Specifications are subject to change without notice. * Refer to the Specification Definitions immediately following the Pin Description Section.
