SensorPath INTERFACE FOUR ADDRESSES RESOLUTION: +0.25 C (10-bit) WIDE TEMPERATURE RANGE: -40 C to +125 C LOW QUIESCENT CURRENT: 110uA (typ) TEMPERATURE ACCURACY: 2 C (max) EXTENDED SUPPLY RANGE: +2.7V to +5.5V MICRO-SIZE PACKAGES: SOT23-6 or MSOP-8

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.
