Hello

I input TSENSE of AD5560 from MEASOUT into ADC 7689, and int 21234 is returned.

In the specification of AD5560,

Die_Temp = (VMEASOUT (TSENSE) - 1.54) / 0.0047 + 25;

Although it is written, how can we obtain the Celsius temperature

Could you tell me

Hello,

If I assume your AD7689 ADC has a VREF of 5V, then the returned value of 21234 means you have a MEASOUT voltage of ~1.62V. (using Voltage_Reading = ((ADC value)/(0xFFFF))*VREF)

Using the die temperature formula:

Die_Temp = (VMEASOUT_TSENSE - 1.54) / 0.0047 + 25

Die_Temp = (1.62 - 1.54)/0.0047 + 25

Your die temperature should be 42.03 degrees Celsius.
