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.
