DS75LX

Digital Thermometer and Thermostat

with Extended Addressing

www.maxim-ic.com

GENERAL DESCRIPTION

FEATURES

This low-voltage (1.7V to 3.7V) digital thermometer

and thermostat provides 9, 10, 11, or 12-bit digital

temperature readings over a -55°C to +125°C range

with ±2°C accuracy over a -25°C to +100°C range. At

power-up, the DS75LX defaults to 9-bit resolution for

software compatibility with the LM75. Communication

with the DS75LX is achieved through a simple 2-wire

serial interface. Three tri-state address pins allow up

to 27 DS75LX devices to operate on the same 2-wire

bus, which greatly simplifies distributed temperature-

sensing applications.

1.7V to 3.7V Operating Range

Tri-State Address Pins Allow Up to 27 Unique

Bus Addresses

Temperature Measurements Require No

External Components

Measures Temperatures from -55°C to +125°C

(-67°F to +257°F)

±2°C Accuracy from -25°C to +100°C

Thermometer Resolution Is User-

Configurable from 9 (Default) to 12 Bits (0.5°C

to 0.0625°C Resolution)

9-Bit Conversion Time is 25ms (max)

Thermostatic Settings are User-Definable

Data is Read/Written Through 2-Wire Serial

Interface (SDA and SCL Pins)

Data Lines Filtered Internally for Noise

Immunity (50ns Deglitch)

The DS75LX thermostat has a dedicated open-drain

output (O.S.) and programmable fault tolerance,

which allow the user to define the number of

consecutive error conditions that must occur before

O.S. is activated. There are two thermostatic

operating modes that control thermostat operation

based on user-defined trip-points (T_OSand T_HYST).

Bus Timeout Feature Prevents Lockup

Problems on 2-Wire Interface

Multidrop Capability Simplifies Distributed

Temperature-Sensing Applications
