3 Description
The TMP102-Q1 device is a digital temperature
sensor ideal for NTC and 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 SOT23 package. The
TMP102-Q1 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 V to 3.6 V with
the maximum quiescent current of 10 µA over the full
operating range.
The TMP102-Q1 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-Q1 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.
