The TMP112-Q1 and TMP112D-Q1 devices are digital temperature sensors designed for NTC/PTC thermistor replacement where high accuracy is required. These devices offer an accuracy of ±0.4°C/±0.5°C without requiring calibration or external component signal conditioning. TMP112-Q1 and TMP112D-Q1 are highly linear and do not require complex calculations or lookup tables to derive the temperature. The calibrating for improved accuracy feature in TMP112-Q1 (see the Calibrating for Improved Accuracy section) allows users to calibrate for an accuracy as good as ±0.17°C. The on-chip 12-bit ADC offers resolutions down to 0.0625°C.

TMP112-Q1 and TMP112D-Q1 come with 0.8mm × 0.8mm X2SON (DPW) and 1.6mm × 1.6mm SOT563 (DRL) packages. These devices feature SMBus™, two-wire and I2C interface compatibility, and allow up to four devices on one bus along with SMBus alert function. These devices are specified to operate over 1.4V to 3.6V supply voltage. The maximum quiescent current is around 10µA over the full operating range.
