MAX31856 in MAX31855 Thermocouple Amplifier Family
The MAX31856, manufactured by Analog Devices (formerly Maxim Integrated), is a precision thermocouple-to-digital converter that simplifies high-accuracy temperature sensing. Unlike its predecessor the MAX31855, this IC supports multiple thermocouple types including K, J, N, R, S, T, E, and B using a single design. It integrates cold-junction compensation, a 19-bit analog-to-digital converter, and a flexible SPI interface, making it a robust solution for industrial systems requiring high resolution and fault detection capabilities.
Variants in This Sub-Family
Variants within the MAX31856 family primarily differ in packaging options and shipping formats, such as the 14-pin TSSOP package. While the core silicon remains consistent across the series, selection often depends on temperature grading (industrial versus automotive) and whether the part is supplied in bulk tubes or tape-and-reel (denoted by +T suffixes) for automated surface-mount assembly processes.
