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

The 1.6-mm × 1.6-mm SOT563 package is 68% smaller footprint than an SOT23 package. The TMP112-Q1 device features SMBus™, two-wire and I2C interface compatibility, and allows up to four devices on one bus. The device also features an SMBus alert function. The device is specified to operate over supply voltages from 1.4 to 3.6 V with the maximum quiescent current of 10 µA over the full operating range.
