Complete Thermocouple Interface Designs Eliminate External
Components, Use Less Space
DS600, MAX1416, MAX6133, MAX31855
The thermocouple circuit shown in
Figure 1 uses the MAX1416 ADC
that allows direct interfacing with
thermocouples, thereby eliminating
external components and reducing
the overall footprint. The internal PGA
eliminates the need for an external
precision amplier; self-calibration
avoids expensive calibration procedures
during manufacture. The MAX1416
accommodates negative temperatures
because its input common-mode
range extends 30mV below ground.
Cold-junction temperature is measured
using a DS600 analog temperature
sensor located at the thermocouple
connector. With ±0.5°C accuracy, the
DS600 provides the most accurate cold-
junction compensation of any analog
temperature-sensor IC on the market.
Adding the cold-junction temperature to
the temperature measured by the ADC
corrects for the parasitic thermocouples
created when the thermocouple
connector is linked to the system.
