3 Description

The TMP107-Q1 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-Q1 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-Q1 is ideal for replacing NTC and PTC thermistors where high accuracy is required.
