Description
Maxim Integrated MAX31850 / MAX31851 cold junction compensated 1-wire Thermocouple to Digital Converters are accurate thermocouple-to-digital converter ICs that ease design effort and lower system cost. The 1-wire interface simplifies multi-thermocouple systems with minimal wiring. Each device has a unique 64-bit serial code stored in an on-board ROM. They also feature four pin-programmable bits to uniquely identify up to 16 sensor locations on a bus. MAX31850 / MAX31851 simplify system fault management and troubleshooting by detecting thermocouple shorts to GND or VCC. These devices also detect open thermocouple. They are ideal for use in a variety of applications, including precision industrial thermal monitoring, medical equipment, solar equipment, automotive, and more.
