At frequencies below 10 kHz, THD degrades to –80 dB and SFDR degrades to –83 dB. 6See Figures 23 and 24 for information regarding the number of filter taps allowed and the current consumption as the CLKIN frequency is varied. 7The AD7725 can operate with an external reference input in the range of 1.2 V to 3.15 V. 8Guaranteed by the design. 9Gain Error excludes reference error. 10All I DD tests are done with the digital inputs equal to 0 V or DV DD. 11Analog current does not vary as the CLKIN frequency and the number of filter taps used in the postprocessor is varied. 12If HALF_PWR is logic low, AI DD will typically double. 13Digital current varies as the CLKIN frequency and the number of filter taps used in the postprocessor is varied. See Figures 23 and 24. 14Digital inputs static and equal to 0 V or DV DD. Specifications subject to change without notice.
