3 Description
The TMP102 device is a digital temperature sensor
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. 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 1.6-mm × 1.6-mm 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 1.4 to 3.6 V with the maximum
quiescent current of 10 µA over the full operating
range.
The TMP102 device is ideal 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.
