The TMP105 is a two-wire, serial output temperature sensor available in a WCSP package. Requiring no external components, the TMP105 is capable of reading temperatures with a resolution of 0.0625°C.

The TMP105 features a Two-Wire interface that is SMBus-compatible, with the TMP105 allowing up to two devices on one bus. The TMP105 features an SMBus Alert function.

The TMP105 is ideal for extended temperature measurement in a variety of communication, computer, consumer, environmental, industrial, and instrumentation applications.

The TMP105 is specified for operation over a temperature range of –40°C to +125°C.
