AD7616 Diagnostics

The calculated Vcc and LDO code results from the transfer functions are diifference from Figure66 and Figure67.
ex. Vref=2.5V ,Vcc=5V : Vcc code= ((4xVcc)-Vref)x32768/(5xVref)=((4x5)-2.5)x32768/(5x2.5)=45875.2
Figure66 Vcc=5V : Expected output is around 25500.
What is differece of these results?

Hi,

The Diagnostic Channel section of the AD7616 datasheet may not have much details on the formula. The formula must use the 4.096V Reference voltage.

Regards,

Jonathan
