AD592 Temperature Sensor

Yes,

Any tips / advice would be helpful.

I have ad592 temperature sensor. I have it working and calibrated correctly, but could someone give me some tips on how to get the increments less. It currently jumps 1 degree C at a time. If this is not possible could someone help me convert the celcius to farenheit as the stamp will not do deciaml numbers. Any help would be appreciated. If i need another sensor that might be a step I have to take to measure tenths of a degree.

Thanks,
Allen

The output is 1uA/K and the change between 0c and 70c is only 70uA so you will need some form of amplication to get better response. The datasheet shows how to use resistors to convert to 1mV/K so that would be a start. Also higher resolution ADC and a precision reference voltage will help.
