Thermocouple Amplifier

[banjohamster]

Hi folks,

Does anyone know of a cold-junction compensated thermocouple amplifier IC that gives an analogue output, and that will run from ~3.3Vdc? My typical go-to is the AD595, but that requires 5vdc. A 3.3vdc alternative is the MAX31855, but this gives a digital output, and will take up too many of my valuable DIO pins on my controller.

Any help gratefully appreciated.

Something in the AD8494 / AD8495 / AD8496 / AD8497 series, maybe ?

Merely my Google-Fu. Good luck.
