Texas Instruments  TMP104YFFR

The TMP104 device is a digital output temperature sensor in a four-ball wafer chip-scalepackage (WCSP). The TMP104 is capable of reading temperatures to a resolution of 1°C.

The TMP104 features a SMAART wire™ interface that supports daisy-chain configurations. Inaddition, the interface supports multiple device access (MDA) commands that allow the master tocommunicate with multiple devices on the bus simultaneously, eliminating the need to sendindividual commands to each TMP104 on the bus.

Up to 16 TMP104s can be tied together in parallel and easily read by the host. TheTMP104 is especially ideal for space-constrained, power-sensitive applications with multipletemperature measurement zones that must be monitored.

The TMP104 is specified for operation over a temperature range of –40°C to +125°C.
