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. Diode Temp. Sensor ∆Σ A/D Converter OSC Control Logic Serial Interface Config. and Temp.
