Remote ±±1° Accurate Diꢀital ꢁemperature

Sensors with SPI-°ompatible Serial Interface

7/MAX628

General Description

Features

o Accuracy

The MAX6627/MAX6628 precise digital temperature

sensors report the temperature of a remote sensor. The

remote sensor is a diode-connected transistor, typically

a low-cost, easily mounted 2N3904 NPN type that

replaces conventional thermistors or thermocouples.

The MAX6627/MAX6628 can also measure the die tem-

perature of other ICs, such as microprocessors (µPs) or

microcontrollers (µCs) that contain an on-chip, diode-

connected transistor.

1°C (max) from 0°C ≤ T ≤ +125°C, T = +30°C

2.4°C (max) from -55°C ≤ T ≤ +100°C,

0°C ≤ T ≤ +70°C

o 12-Bit + Sign, 0.0625°C Resolution

o Low Power Consumption

30µA (typ) (MAX6628)

200µA (typ) (MAX6627)

o Operating Temperature Range (-55°C to +125°C)

Remote accuracy is ±±1C when the temperature of the

remote diode is between 01C and +±251C and the tem-

perature of the MAX6627/MAX6628 is +301C. The tem-

perature is converted to a ±2-bit + sign word with

0.06251C resolution. The architecture of the device is

capable of interpreting data as high as +±451C from

the remote sensor. The MAX6627/MAX6628 tempera-

ture should never exceed +±251C.

o Measurement Temperature Range, Remote

Junction (-55°C to +145°C)

o 0.5s (MAX6627) or 8s (MAX6628) Conversion Rate

o SPI-Compatible Interface

o +3.0V to +5.5V Supply Range

o 8-Pin SOT23 and TDFN Packages

o Lead-Free Version Available (TDFN Package)

These sensors are 3-wire serial interface SPI™ compat-

ible, allowing the MAX6627/MAX6628 to be readily con-

nected to a variety of µCs. The MAX6627/MAX6628 are

read-only devices, simplifying their use in systems

where only temperature data is required.

Two conversion rates are available, one that continu-

ously converts data every 0.5s (MAX6627), and one

that converts data every 8s (MAX6628). The slower ver-

sion provides minimal power consumption under all

operating conditions (30µA, typ). Either device can be

read at any time and provide the data from the last con-

version.

*EP = Exposed pad.

Both devices operate with supply voltages between

+3.0V and +5.5V, are specified between -551C and

+±251C, and come in space-saving 8-pin SOT23 and

lead-free TDFN packages.
