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 best accuracy of ±0.4°C (TMP112D-Q1) or ±0.5°C (TMP112-Q1) 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.

The TMP112-Q1 is offered only in the SOT563 (DRL) package, whereas the TMP112D-Q1 provides enhanced performance and is available in both the SOT563 (DRL) and the smaller X2SON (DPW) packages. Dedicated pins are available on the SOT563 package for ALERT and address functions, while the center pin on the X2SON package supports either function depending on the orderable part number. The devices operate over a supply voltage range of 1.4V to 3.6V for the TMP112-Q1 and 1.4V to 5.5V for the TMP112D-Q1. The maximum quiescent current is around 10µA over the full operating range.
