3 Description
The TMP275-Q1 is a ±0.75°C, accurate integrated
digital temperature sensor with a 12-bit, analog-todigital
converter (ADC) that can operate on a supply
voltage as low as 2.7 V and is pin- and registercompatible
with the Texas Instruments' LM75,
TMP75, TMP75B, and TMP175 devices. The
TMP275-Q1 device is available in 8-pin SOIC and
VSSOP packages and requires no external
components to sense temperature. The device is
capable of reading temperatures with a maximum
resolution of 0.0625°C (12 bits) and as low as 0.5°C
(9 bits), thus allowing the user to maximize efficiency
by programming for higher resolution or faster
conversion time. The device is specified over the
temperature range of –40°C to +125°C.
The TMP275-Q1 device features SMBus and twowire
interface compatibility and allows up to eight
devices on the same bus with the SMBus
overtemperature alert function. The factory-calibrated
temperature accuracy and the noise-immune digital
interface make the TMP275-Q1 the preferred solution
for temperature compensation of other sensors and
electronic components, without the need for
additional system-level calibration or elaborate board
layout for distributed temperature sensing.
