Have you searched for "thermocouple " ? Here is an example from cookbook https://mbed.org/cookbook/MAX6675-Thermocouple

Regards, Christos

yup. i have searched it but max 6675 and k type thermocouple specifications are different.and the code for max doesn't work for k type thermocouple.

Use MAX31855. There is a device for K type thermocouple.

i have designed amplifier using CA3140.

Yes Peter is right , it seems that 31855 is an update for 6675 which is NRND: Not recommended for new designs. Have a look at this as well http://mbed.org/users/Stavlin/code/MAX31855/ and perhaps update the cookbook ...

edit : The 3140 is the difficult way ... !
