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 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.
The TMP141 is a digital output temperature sensor that utilizes the single-wire SensorPath interface. It measures temperatures within 2°C of accuracy over a range of -25°C to +85°C and 3°C of accuracy over -40°C to +125°C. The device requires no external sensing components and is available in SOT23-6 and MSOP-8 packages.
The sensor operates with a supply voltage range from 2.7V to 5.5V and features a low quiescent current of 110 µA (typical). Up to four TMP141 devices can be attached to a single SensorPath bus, allowing a master device to configure and read temperature outputs from all connected devices simultaneously.
