TLA2024: Device reading .5 V less than expected.

Part Number: TLA2024

I am using a TLA2024 ADC to monitor battery voltage int the range of 1.5V - 2.1V. I have found that the device outputs values consistently .5V less than would be expected. Is there a reason I may be having this issue?

Thanks

    Hello John,

    Can you share your schematic? Are you measuring single-ended or differential voltages, and what is your supply voltage? Also, what is the FSR that you have configured the device for? Finally, can you provide an example of the input voltage measured externally with a DMM and the resulting output code for that input in your system?


    Thank you,

    Scott
