Hi

We have 10 ADT7310 Temp.Sensors who works on 10 prototyps.

But we have following problems.

The ADT7310 works not in spezification of repeatability !!

All 10 Prototypes have the same problems on different temperatur !

Sensor 1-8 : (Ramp-up Temp. 5-80°C) only at 50°C the ADT7310 is out of spezification (repeatability +/-0.5°C !!!)

Sensor 9 : (Ramp-up Temp. 5-80°C) only at 38°C the ADT7310 is out of spezification (repeatability +/-0.5°C !!!)

Sensor 10 : (Ramp-up Temp. 5-80°C) only at 40°C and 80°C the ADT7310 is out of spezification (repeatability +/-0.5°C !!!)

 

On all other Temp. the ADT7310 works fine and are in specification !

 

The ADT7310 works in continiouse Mode and every 300ms we read the Temp. from the temp.value register.

 

have everyone an idea whats the problem is? Or have everyone the same problem ?

 

Thanks for help

Roger
