ADS8689W: ADS868xW current consumption

Frank Herzog95

Part Number: ADS8689W
Other Parts Discussed in Thread: ADS8681W,

ADS868xW datasheet (SBASAY5A, revision date May 2025), page 8, parameter IAVDD_DYN (Analog supply current): 'Internal reference ADS8681W' is listed twice, but 'Internal reference ADS8689W' is missing.

Is it correct to assume that there are several typos in this table? What is the analog supply current of the ADS8689W with the internal reference enabled?

    Hello Frank, 

    This is a good catch, and definitely a typo, thank you for bringing this to our attention! I will submit so this gets corrected in the next revision! 

    The correct order is according to the speed category of the device. The fastest sampling one, the ADS8681W, would consume the most power, while the slowest, ADS8689W the least. 

    I've updated the order for now:

    Best regards,
