Texas Instruments TMP144 Digital Temperature Sensors

Texas Instruments TMP144 Digital Temperature Sensors can read temperatures to a resolution of 0.0625°C. The devices have a SMAART wire™/UART interface that supports daisy-chain configurations. The interface also supports multiple device access (MDA) commands that let the master communicate with multiple devices on the bus simultaneously. MDA commands are used as an alternative to sending individual commands to each device on the bus. Up to 16 TMP144 devices can be attached together in parallel and can be easily read by the host computer.

The TMP144 device is designed for space-constrained, power-sensitive applications with multiple temperature measurement zones that must be monitored. The device is specified for operation over a temperature range of -40°C to 125°C and is available in a four-ball wafer chip-scale package (DSBGA).
