Simplified Schematic

3 Description

The TMP275-Q1 is a ±0.5°C, accurate integrated

digital temperature sensor with a 12-bit, analog-to-

digital converter (ADC) that can operate on a supply

voltage as low as 2.7 V and is pin- and register-

compatible

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 two-

wire 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.
