3 Description

The TMP118 is the industry smallest temperature

sensor in an industry leading 0.55mm × 0.61mm ×

0.24mm PICOSTAR package. The TMP118 provides

a 16-bit temperature result with a resolution of

0.0078125°C and an accuracy of up to ±0.1°C

across the temperature range of 0°C to 50°C with

no additional calibration. The device is designed to

help meet the system level ASTM E1112 and ISO

80601 accuracy requirements for electronic patient

thermometers.

The TMP118 is designed to operate from a supply

voltage as low as 1.4V, with a low average and

shutdown current of 1.4μA (at 1Hz, no averaging)

and 80nA, respectively, allowing for an on-demand

temperature conversion to maximize battery life. The

TMP118 has an interface that is I2C- and SMBuscompatible

and has programmable alert functionality.

Logic level as low as 1V can be supported regardless

of the main supply rail, enabling interoperability with

a low voltage 1.2V controller without an additional

voltage level shifter.

The device offers unique IDs for improved traceability.

The TMP118 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.
