Digital temperature sensor for space-constrained and power-sensitive applications

Texas Instruments TMP144 Digital Temperature Sensor can read temperatures to a resolution of 0.0625C. The device provides a SMAART wire/UART interface that assists daisy-chain configurations. The interface also supports MDA commands that let the master interact with multiple devices on the bus simultaneously. MDA commands are used as an alternative to sending individual commands to every device on the bus. Up to 16 of the devices can be connected in parallel and can be easily read by the host computer. The device is intended for space-constrained, power-sensitive applications with many temperature measurement zones that need to be monitored. The device is specified for operation over a temperature range of –40C to 125C and is offered in a four-ball wafer chip-scale package (DSBGA). The device is ideal for handsets, smartphones, tablets, LED backlighting, HDTVs, enterprise servers, notebooks, and medical applications.
