AD4115 GPIO Input levels

Category: Datasheet/Specs
Product Number: AD4115


An other question about this ADC and the two available GPIOs that can be used as inputs.

I was surprised that the GPIOs are related to analog voltages (wrongfully said to be usable to 3.3V on page 36, which was one of the reasons why we choose this ADC and had to add a 5V line at the last moment..), but there is no information about the characteristics of these lines. We can not use the outputs as we don't have any 5V logic, but perhaps there is a hope to be able to use thee inputs with 3.3V levels.

But the datasheet does not tell what are the low/high levels or these.

Anybody knows or have checked ?

Thanks in advance,

    Hi  ,

    Thank you for bringing this up to us. We will have this corrected on our next datasheet revision. The AD4115 does not support operation at AVDD = 3V. Sorry for the inconvenience it has caused…
