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.
