Reads temperature to +/-0.1 C over a wide range without calibration, in a WSON-6 that talks I2C. Its 16-bit resolution gives 0.0078 C steps, and the accuracy is NIST-traceable, so it stands in for a Class-AA RTD at a fraction of the cost and complexity. An ALERT output supports thermostat limits, and up to four addresses share a bus. It runs from 1.8 to 5.5 V. The precision choice for medical, instrument, and cold-chain temperature.

Pinout

Pin	Name	Type	Function
1	SCL	input	I2C/SMBus serial clock input. Requires an external pullup resistor. Input logic levels VIH ≥ 0.7·V+, VIL ≤ 0.3·V+; max SCL frequency 400 kHz (Fast-Mode).
2	GND	power_in	Device ground reference.
3	ALERT	output	Over-temperature alert or data-ready signal. Open-drain output, requires an external pullup resistor. VOL ≤ 0.4 V at IOL = 3 mA.
4	ADD0	input	I2C address-select input. Tie to GND, V+, SDA, or SCL to select one of four device addresses, allowing up to four devices on a single bus.
5	V+	power_in	Supply voltage input. 1.8 V to 5.5 V over full -55 °C to 150 °C range (1.7 V to 5.5 V for TA ≤ 70 °C); nominal 3.3 V. Bypass with a 0.1 µF ceramic capacitor to GND.
6	SDA	bidirectional	I2C/SMBus serial data. Input and open-drain output; requires an external pullup resistor. Data valid time ≤ 0.9 µs in Fast-Mode.
