3 Description
The TMP116 (TMP116, TMP116N) is a family 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 I²C- and SMBus-interface
compatible, has programmable alert functionality, and
can support up to four devices on a single bus.
The TMP116 consumes minimal current that, in
addition to providing power savings, minimizes self-
heating 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.
