Product Number: AD4695
Hi,
I am trying to get the AD4695 or AD4696 working for a single channel read on the evaluation board AD4696EVAL.
I am getting the unpredictable random results when I read from conversion mode with an SPI interface using a RPICM4 module.
If I tie the channel to ground, I get 0V or very close to zero as I call the read function repeatedly and the read increases if I put a higher voltage on the channel e.g. 5V
The higher voltage readings are sometimes correct, but I am not seeing reliable repeatable results. Sometimes it looks perfect for 5V, other times it's half the value or something in-between.
Have you any insight that you can share as the chip looks very close to working with an SPI interface.
I look forward to your response,
Duncan
