•

High Accuracy (Without Calibration):

supports a total of 32 daisy-chained devices. Each

–

±0.4°C (max) from –20°C to +70°C

sensor

has

a

unique

5-bit

address

stored

in

–

±0.55°C (max) from –40°C to +100°C

electrically-erasable

programmable

memory

(EEPROM). The TMP107 is capable of reading

–

±0.7°C (max) from –55°C to +125°C

temperatures with a resolution of 0.015625°C, and is

•

High Resolution: 14 Bits (0.015625°C)

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

•

UART-Compatible, SMAART Wire™ Interface:

+70°C. The TMP107 is ideal for replacing NTC and

PTC thermistors where high accuracy is required.

–

Allows Up To 32 Daisy-Chained Devices

•

EEPROM Memory for Unique Addressing, Trip

The unique 5-bit address stored in the EEPROM is

Level Programming, and General-Purpose

determined

during

the

automated

address

assignment operation, and is based on the position of

Storage

each sensor relative to the SMAART wire host.
