Thermocouple measurement. Similiar IC from MAX6675.

[xxtigerxx]

I want to measure temperature up to 350C.
So i think the best solution is to use a thermocouple.

I find the MAX6675.

Does anyone knows a more cheap IC?

Analog Devices AD597 with analog output may be cheaper.

I would also like to invite your question to a group dedicated to sensors: **broken link removed**. You should be able to get advice there too.

kender thank for the advise

but the AD597 is more expensive and have analog output.
