Hi,

I'd like to know the internal voltage reference value of this little gem. Sorry If I'm dumb but I can't see it in the datasheet.

Thank you very much.

JustGreg,

The ADS1118 uses a virtual reference that scales from the operating voltage. So the reason you can't find it in the datasheet is that there isn't a specific voltage used as a reference voltage. You determine the LSB size based on the input range selected for the device.

Best regards,

Bob B
