It handles the cold-junction compensation and linearisation internally, so the host MCU sees a temperature reading without an analogue front-end or lookup table. The 900 µA supply current keeps the thermal budget low in multi-channel panels or battery-backed loggers. ## Temperature range and environment Rated for -40°C to 125°C operation. ## Package and footprint Housed in an 8-SOIC package (0.154\" body width, 3.90 mm), it fits a standard SOIC-8 land pattern. The surface-mount profile is compatible with reflow assembly; no special pad geometry or thermal-relief cutouts are required for this 900 µA part. Tape & Reel (TR) and Cut Tape (CT) options are listed, so the same reel feeds both prototype pick-and-place and production runs. ## Lifecycle and supply posture Marked as Active and ROHS3 compliant, so no end-of-life notice is pending from the manufacturer. For a BOM freeze, this is a low-risk line item — no LTB window to track, no substitute qualification to plan.","metaTitle":"MAX31855KASA+T Thermocouple to Digital Converter","metaDescription":"MAX31855KASA+T Thermocouple to Digital Converter from Analog Devices.
