3 Description

The TMP116 family (TMP116, TMP116N) consist of

low-power, high-precision temperature sensors with

integrated EEPROM memory. The TMP116 provides

a 16-bit temperature result with a resolution of

0.0078°C and an accuracy of up to ±0.2°C with no

calibration. The TMP116 is compatible with the I2Cand

SMBus interface, has programmable alert

functionality, and supports up to four devices on a

single bus.

The TMP116 consumes minimal current that, in

addition to providing power savings, minimizes selfheating

and improves measurement accuracy. The

TMP116 operates from 1.9 V to 5.5 V and typically

consumes 3.5 μA.

Across the device operating temperature range of

–55°C to +125°C, the TMP116 exceeds the accuracy

of a class A RTD, while consuming less than one fifth

of the typical excitation current for a PT100 RTD. The

TMP116 is easier to use than RTDs, eliminating the

need for calibration, external circuitry, matched

traces, and Kelvin connections.

The TMP116 units are 100% tested on a production

setup that is NIST traceable and verified with

equipment that is calibrated to ISO/IEC 17025

accredited standards.
