MAX31855KASA+T

MAX31855KASA+T
Cold-Junction Compensated Thermocouple-to-Digital Converter, SO8, Maxim Integrated, RoHS

---

The MAX31855 performs cold-junction compensation and digitizes the signal from a K-, J-, N-, T-, S-, R-, or E-type thermocouple. The data is output in a signed 14-bit, SPI-compatible, read-only format. This converter resolves temperatures to 0.25°C, allows readings as high as +1800°C and as low as -270°C, and exhibits thermocouple accuracy of ±2°C for temperatures ranging from -200°C to +700°C for K-type thermocouples.

Features:

• Cold-Junction Compensation
• 14-Bit, 0.25°C Resolution
• Versions Available for K-, J-, N-, T-, S-, R-, and E-Type Thermocouples
• Simple SPI-Compatible Interface (Read-Only)
• Detects Thermocouple Shorts to GND or VCC
• Detects Open Thermocouple
