Hi Angel, Sorry about that, the 0x900e is old content in my reply, I had updated my reply to replace 0x900e with 0xd017, but I missed updating the last sentence. [quote userid="556660" url="~/support/data-converters-group/data-converters/f/data-converters-forum/1430965/tla2024-i-got-the-negative-value-double-confirm-the-way-of-read-the-result-register-and-conversion/5501849#5501849"]The following table in the data sheet shows in detail how to convert between input signal voltage and output digital values:[/quote] We did, but it shows the output value goes negative, it doesn't match the value we designed and measured by the oscilloscope. That's why we need you to confirm the conversion. Do you confirm my conversion in my first reply?

I think we have verified the value from i2cget which match the value from ADC result register, am I right?

Or you can point out which steps we are doing wrong?
