That ±1°C is the highest accuracy spec over the entire industrial temperature window — not just a narrow sweet spot — so it holds up in an engine bay or outdoor cabinet without recalibration. It communicates over I²C/SMBus, which means a standard two-wire interface with the host MCU. The output type (I²C/SMBus) and the 12-bit resolution are fixed — no pin-strapping for address or bus speed, so the firmware just reads the temperature register. Supply voltage range of 1.4V to 3.6V means this sensor can operate directly on a 1.8V or 3.3V rail without a separate LDO. That saves a regulator and a decoupling cap on a dense board. The low 1.4V minimum also supports single-cell Li-ion or LiFePO4 battery-powered designs down to near-end-of-discharge. The sensor draws minimal current in shutdown mode (listed under features: One-Shot, Output Switch, Shutdown Mode), which makes it suitable for battery-backed telemetry or IoT nodes that wake, take a reading, and go back to sleep. ## Active production — SOT-563 tape and reel It ships in Tape & Reel (TR) or Cut Tape (CT) options, in the SOT-563 package (also listed as SOT-666 and SOT-5X3 supplier device package). ## One-Shot, shutdown, and output switch features The TMP112NAIDRLT includes a One-Shot mode that lets the host trigger a single conversion and then return the sensor to shutdown, minimizing average current. The Output Switch feature can be configured as a comparator or thermostat interrupt — useful for overtemperature alerts without polling the I²C bus. The local sensing range matches the operating temperature: -40°C to 125°C.","metaTitle":"TMP112NAIDRLT – ±1°C Digital Temp Sensor, I²C, SOT-563","metaDescription":"Texas Instruments TMP112NAIDRLT: ±1°C accuracy, -40°C to 125°C, 1.4V-3.6V supply, I²C/SMBus output.
