DS75LV

Digital Thermometer and Thermostat

General Description

Beneﬁts and Features

● Extend Performance Range with Low-Voltage,

The DS75LV 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 DS75LV

defaults to 9-bit resolution for software compatibility with the

LM75. Communication with the DS75LV is achieved through

a simple 2-wire serial interface.

1.7V to 3.7V Operating Range

● Maximize System Accuracy in Broad Range of

Thermal Management Applications

• Measures Temperature from -55°C to +125°C

(-67°F to +257°F)

• ±2°C Accuracy over a -25°C to 100°C Range

• User-Conﬁgurable Resolution from 9 Bits (Default)

to 12 Bits (0.5°C to 0.0625°C)

The DS75LV thermostat has a dedicated open-drain output

(OS) and programmable fault tolerance, which allows the

user to define the number of consecutive error conditions that

must occur before OS is activated. There are two thermostatic

operating modes that control thermostat operation based on
