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.
