Data register value

Hello,

 

I am acquiring temperature data from a sensor and using AD7794 for signal conditioning. I find the analog value of the temperature increasing with rise in temperature. But I find digital data corresponding to the temperature to be decreasing.

I am using unipolar mode and channel 2 (AIN2) for temperature acquisition.

I have checked the polarity of the signal. Pin9 of AD7794 is connected to temperature sensor output and pin10 is grounded with a resistor. Please let me know why is this happening.

 

Thanks in advance!
