ADAU1701 Supply voltage Min./Max. values.
The ADAU1701 has only typical values for the Supply voltage.
But when designing the board, we need to know the Min./Max. values.
In the data sheet, page 6 table 3, we can find following note.
Can we treat these values as the Min. and Max. values?
1.62 V and 1.98 V for the DVDD, 2.97 V and 3.63 V for the AVDD/PVDD/IOVDD.
>1 Maximum specifications are measured across a temperature range of −40°C to +130°C (case),
> a DVDD range of 1.62 V to 1.98 V, and an AVDD range of 2.97 V to 3.63 V.
I checked other parts, ADAU1761 and ADAU146x. For these parts, Min/Max values are specified, and they have similar values ...

Hello Euglena,
You are correct. The measured MAX specifications give a clue as to what we expect and what we test the part to. That would be +/- 10%. The you can use the numbers you found in the note. If you keep the power supplies to within 10% the part will function correctly.

Dear Dave,
Thanks for your quick reply.
I clearly understood. I would like to use the values written in the note as the Min./Max.
