ADS1118: thermocouple temperature sensing from -50 degree to 200 degree C

Part Number:ADS1118

Hi, my customer need to measure the temperatue of the battery cell, and they need the temperature accuracy is at least 1°C at range of -50 to 200°C。They want to use T type thermocouple and cold junction compensation is needed.

I've searched some reference design below but it seems none of them 100% matches their need. The competitor is LTC2983 or AD595 from ADI.

Which solution do you think is best to promote?
