DS1631/DS1631A/

DS1731

High-Precision Digital

Thermometer and Thermostat

General Description

Beneﬁts and Features

The DS1631, DS1631A, and DS1731 digital thermome-

ters provide 9, 10, 11, or 12-bit temperature readings over

a -55°C to +125°C range. The DS1631 and DS1631A

thermometer accuracy is ±0.5°C from 0°C to +70°C with

● Maximize System Accuracy in Broad Range of

Thermal Management Applications

• Operating Temperature Range: -55°C to +125°C

(-67°F to +257°F)

• DS1631 and DS1631A: ±0.5°C Accuracy over 0°C

to +70°C Range

3.0V ≤ V

from -10°C to +85°C with 3.0V ≤ V

≤ 5.5V, and the DS1731 accuracy is ±1°C

≤ 5.5V. The ther-

• DS1731: ±1°C Accuracy over a -10°C to +85°C Range

• User-Selectable Output Resolution from 9 Bits to

12 Bits

mostat on all three devices provides custom hysteresis

with user-defined trip points (T and T ). The T and

T registers and thermometer configuration settings are

stored in NV EEPROM so they can be programmed prior

to installation. In addition, the DS1631A automatically

begins taking temperature measurements at power-up,

which allows it to function as a stand-alone thermostat.

● Reduce Cost with No External Components

● Simplify Distributed Temperature-Sensing Applications

with Multidrop Capability

• Up to Eight Devices Can Operate on a 2-Wire Bus

Pin descriptions for the DS1631/DS1631A/DS1731 are pro-

vided in Table 2 and user-accessible registers are summa-

rized in Table 3. A functional diagram is shown in Figure 1.

● Flexible and Nonvolatile User-Defined Thermostatic

Modes with Custom Hysteresis

● Available in 8-Pin µSOP and SO (DS1631 and

DS1631A Only) and the 8-Pin DIP (DS1631 Only)

Packages

Applications

● Network Routers and Switches

● Cellular Base Stations

● Portable Products

● Any Space-Constrained Thermally Sensitive Product
