AD595 Proteus Simulation Problem

dmw · Oct 12, 2014

Hi People I m new to this site and wanted to ask a few questions regarding the AD595 thermocouple set up. I have set up a simulation circuit in proteus using a Ad595 with a thermocouple attached the out put readings I am getting are 250mV @ 0 degree C and 498 @ 25 degree C. Looking at the data sheet it suggests that I should be getting 250mV @ 25 degree C. cold anyone comment of why this may be the different here ?

Any help would be much appreciated.

I have posted a AD595 Proteus project here. It is under the name jayanth.devarayanadurga Search for it and use it. Also Zip and post your complete project files.

Hi Milan,

I managed to solve the said problem. It was the fact that the chip had an offset of 25 degrees C. When you double click on the chip it has an initial value of 25 degrees C I just replaced this with 0 degrees C and I then got the required 250 mv output for an input of 25 degree C.
