Texas Instruments  TMP104YFFT

The TMP104 is a digital output temperature sensor in a four-ball wafer chip-scale package (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. In addition, the interface supports multiple device access (MDA) commands that allow the master to communicate with multiple devices on the bus simultaneously, eliminating the need to send individual commands to each TMP104 on the bus.

Up to 16 TMP104s can be tied together in parallel and easily read by the host. The TMP104 is especially ideal for space-constrained, power-sensitive applications with multiple temperature measurement zones that must be monitored.

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