Questions answered in these manuals
What does the automatic power‑down mode do?
When enabled, the AD7823 powers down automatically at the end of a conversion and wakes up on the next conversion start, reducing power consumption.
What is the maximum input leakage current?
The input leakage current is ±1 µA max.
What is the typical conversion time of the AD7823?
The AD7823 converts an input in about 4 µs (typical).
How much power does the AD7823 use at 10 kSPS?
At a throughput of 10 kSPS the device consumes roughly 570 µW.
