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.
