Texas Instruments TMP112/TMP112-Q1 Digital Temperature Sensor is a digital temperature sensor that is ideal 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. IC 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 1.6mm×1.6mm SOT563 package is 68% smaller footprint than an SOT23 package. The TMP112 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 TMP112 production units are 100% tested against sensors that are NIST-traceable and are verified with equipment that are NIST-traceable through ISO/IEC 17025 accredited calibrations. The TMP112-Q1 devices are AEC-Q100 qualified for automotive applications.
