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癈 of
accuracy over a temperature range of 25癈 to +85癈 and
3癈 of accuracy over 40癈 to +125癈. 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.
