With regards ADUC7023 i2C no ACK and Stop

Hi , 

We are using ADUC7023 , when we reduce the temperature we see that master doesn't not issues clocks for ACK and STOP . 

We are using internal clock to run ADUC7023 , Clock input pin is grounded . 

If the Ground has 60-70mV will we have such problems . 

We have pulled the SCL and SDA pin with 4.7k .

Thanking you 

With best regards and wishes
