DESCRIPTION

The TMP141 is a digital output temperature sensor that

utilizes the single-wire SensorPath interface. The TMP141

is capable of measuring temperatures within 2°C of

accuracy over a temperature range of −25°C to +85°C and

3°C of accuracy over −40°C to +125°C. Low supply

current, and a supply range from 2.7V to 5.5V, make the

TMP141 an excellent candidate for a wide range of

low-power applications. The TMP141 is available in

SOT23-6 and MSOP-8 packages.

The TMP141 provides a simple, low-cost way to do

temperature measurement/monitoring and is ideal as a

part of an overall hardware health monitoring system. Up

to four TMP141s can be attached to a SensorPath bus. A

master configures the TMP141s and reads the

temperature output from all devices. No external sensing

components are needed for the TMP141 to measure and

report temperature.
