The data sheet shows 21mW PD @ 250kSPS, and aludes to 17uW @ 1kSPS but I cannot find any
graphs in the data sheet to support this. Is the data available I can use to support the 17uW PD at the lower sample rate?
There is a graph of Operating current vs. Sampling rate on page 23 figure 35 in the datasheet. From this graph, you can dictate the 17uW(power = voltage x current) @ 1ksps using the external reference and VDD = 2.5V.
I moved this question about the AD7682 to the Precision ADCs community. Someone here should be able to assist you.

Guess I didn’t dig deep enough – was looking for it with all the other charts.
