Thermocouple front-end for cold-junction-compensated readings
The MAX31850JATB+ is a thermocouple-to-digital converter from Analog Devices that accepts multiple thermocouple types and outputs a digital temperature reading, handling the cold-junction compensation on-chip. Drawing only 900 µA from the supply, it fits into low-power instrumentation or battery-backed data-logger designs where every microamp counts.
The surface-mount footprint keeps the thermocouple junction close to the PCB, minimising the loop area for noise pickup on the millivolt-level input.
