Measures temperature to +/-0.2 C without calibration over the common range, in a WSON-6 that talks I2C. Sixteen-bit resolution gives 0.0078 C steps, the accuracy is NIST-traceable so it stands in for a Class-A RTD, and a small on-chip EEPROM stores calibration or an ID. An ALERT output supports thermostat limits and up to four addresses share a bus. It runs from 1.9 to 5.5 V at a few microamps. The lower-cost sibling of the TMP117 for accurate ambient and board sensing.

Pinout

Pin	Name	Type	Function
1	SCL	input	Serial clock input for the SMBus/I2C-compatible two-wire interface. Requires an external pullup resistor. Supports up to 400 kHz.
2	GND	power_in	Ground reference for the device. Connect to system ground.
3	ALERT	output	Overtemperature alert or data-ready signal. Open-drain output; requires an external pullup resistor if used. VOL = 0.4 V max at IOL = 3 mA.
4	ADD0	input	I2C address select pin. Connect to GND, V+, SDA, or SCL to select one of four device addresses (allows up to four TMP116 devices on the same bus).
5	V+	power_in	Positive supply voltage input. Operating range 1.9 V to 5.5 V (nominal 3.3 V). Bypass with a 0.1 µF capacitor to GND close to the pin.
6	SDA	bidirectional	Serial data input and open-drain output for the SMBus/I2C-compatible two-wire interface. Requires an external pullup resistor. VOL = 0.4 V max at IOL = 3 mA.
