I have an application where I want to measure 40-80 k type thermocouples for temperature control and overtemperature protection. I played with the ADS1118 eval kit and this part seems to work well for my application (measuring low temperatures < 250 degC, only requires +/-1 deg, low speed). I want to know if TI offers either:
1) a reference design for addressing multiple ADS1118s on one set of SPI lines, toggling the chip selects
-or-
2) a different a/d part that can read 4-8 thermocouples with built in CJC, etc. and a reference design
Thanks
