TMP107 Digital Temperature Sensors

Texas Instruments' TMP107 digital output temperature sensors support a total of 32 daisy-chained devices. Each sensor has a unique 5-bit address stored in electrically erasable programmable memory (EEPROM). The TMP107 are capable of reading temperatures with a resolution of 0.015625°C and are accurate to within ±0.4°C in the range from -20°C to 70°C. The TMP107 are ideal for replacing NTC and PTC thermistors where high accuracy is required.

The unique 5-bit address stored in the EEPROM is determined during the automated address assignment operation, and is based on the position of each sensor relative to the SMAART Wire™ host. Multiple operating modes provide maximum flexibility in selecting between low power consumption for battery operation and high update rates for real-time control applications.

The TMP107 are ideal for extended temperature measurement in a variety of industrial, instrumentation, communication, and environmental applications. The TMP107 are available in an 8-pin SOIC package and are specified for operation over a temperature range of -55°C to 125°C.
