The TMP118 is an ultra-small, ultra-thin digital temperature sensor in a PicoStar™ package, with an area of 0.336mm2, and a maximum height of 240µm. The TMP118 has 16-bit resolution with an LSB of 7.8125m°C, achieving ±0.1°C (max accuracy) from 20°C to 50°C with no additional calibration, which helps meet the system level ASTM E1112 and ISO 80601 accuracy standard for medical-grade electronic thermometers.
Designed for low-power operation, the TMP118 operates from supply voltages as low as 1.4V (up to 5.5V) and draws 55µA when actively converting (approximately 1.4µA at a 1Hz sample rate) and 65nA in shutdown mode, enabling on-demand measurements while maximizing battery life in portable or wearable devices. The TMP118 has an interface that is I2C- and SMBus-compatible and has programmable alert flag functionality. The sensor also supports logic levels down to 1.2V without requiring a level shifter, allowing direct interfacing with low-voltage MCUs.
Additionally, each TMP118includes a unique device ID for NIST traceability. All units are factory-tested with NIST-traceable equipment calibrated to ISO/IEC 17025 accredited standards.
