It draws 900 µA supply current, making it suitable for battery-powered or loop-powered temperature measurement systems where power budget is tight. Rated for -40°C to 125°C operating temperature, this converter fits industrial process control, engine bay monitoring, and outdoor equipment where the ambient sees wide thermal swings. ## Supply current and temperature range — what they mean for your BOM The 900 µA supply current is the active conversion current — not a standby figure. The -40°C to 125°C range covers both cold-crank startup and under-hood heat soak. ## Package and mounting — board-fit details Housed in an 8-SOIC package (0.154\" body width, 3.90 mm), the MAX31855TASA+ uses a standard surface-mount footprint shared by countless 8-pin SOIC parts. The supplier device package is also 8-SOIC, so no footprint surprise between the case code and the supplier code. Shipping medium is Tube — not Tape & Reel. If your pick-and-place line is set up for reel feed, factor in a tube-to-reel transfer or order the tape-and-reel variant if one exists in the family. ## Lifecycle and compliance The MAX31855TASA+ carries an Active lifecycle status and is ROHS3 compliant.","metaTitle":"MAX31855TASA+ Thermocouple to Digital Converter, 8-SOIC","metaDescription":"MAX31855TASA+ thermocouple to digital converter from Analog Devices. 900 µA supply, 8-SOIC package, -40°C to 125°C range.
