3 Description

The TMP107 digital output temperature sensor

supports a total of 32 daisy-chained devices. Each

sensor has a unique 5-bit address stored in

electrically-erasable programmable memory

(EEPROM). The TMP107 is capable of reading

temperatures with a resolution of 0.015625°C, and is

accurate to within ±0.4°C in the range from –20°C to

+70°C. The TMP107 is 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 is ideal for extended temperature

measurement in a variety of industrial,

instrumentation, communication, and environmental

applications. The TMP107 is available in an 8-pin

SOIC package and is specified for operation over a

temperature range of ?55°C to +125°C.
