MAXIM MAX31856 Quad Thermocouple to Digital Converter Board
19-Bit resolution, multiple TC Type options, 3.3-5V Compatible (Arduino, RPi)
Description:
Next in the evolution of Maxim-Integrated's lineup of thermocouple interface ICs, we introduce the Quad MAX31856 Thermocouple to Digital Converter Interface Board! This is an exciting update of the MAX31855, with improvements in resolution (19 vs 14 bits), on-board temperature reference (6 vs 4 bits), compensation (fully compensated vs nonlinear correction required) and a whole host of new internal features to get your precision temperature measuring project off to a solid start. The MAX31856 is interfaced via 4-wire SPI with options for interrupt triggering. An onboard LDO keeps the MAX31856 ICs supplied, while high-speed level shifters are included on ALL device pins to allow interfacing to virtually any development platform, from Arduino to PIC to Raspberry Pi, that operate between 3.3V and 5.0V. In addition, we are offering many connector options to cover virtually any need. Take a look at the options and let us know if you need something that isn't listed!
As always, an Arduino example sketch and library are available for free download from Github.
