Hai Jonathan,
Thank you for your response.
In the attached document the output data in 2's complement in decimal form, before converting to voltage is also added.
Please refer and verify.
Please aslo make sure that the input voltage, and reference pins are consistent. By the way what is the resolution of the signal source that was used? Were there other components connected to the Vin+ and Vin - pins?
Yes, the input voltage and reference pins are consistent.
You can make sure that no component is connected to the Vin+ and Vin- pins.
I am using Aplab's Regulated DC Power Supply L3205 as signal source. I am sorry but I am not sure with the resolution.
Regards,
Lakshmi.
