Cold-junction compensated thermocouple interface in 8-SOIC
It draws 900 µA supply current, making it suitable for battery-powered or loop-powered temperature measurement systems where power budget is tight.
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.
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.
