2C digital temperature sensor, I2C/SMBus in 2.56mm2 package

The TMP102 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 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 SOT-23 package. The TMP102 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 1.4V to 3.6V with the maximum quiescent

current of 7.5µA over the full operating range.

The TMP102 device is designed for extended

temperature measurement in a variety of communication, computer, consumer, environmental,

industrial, and instrumentation applications. The device is specified for operation over a

temperature range of –40°C to 125°C.

The TMP102 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.
