3 Description
The TMP103 is a digital output temperature sensor in
a four-ball wafer chip-scale package (WCSP). The
TMP103 is capable of reading temperatures to a
resolution of 1°C.
The TMP103 features a two-wire interface that is
compatible with both I²C and SMBus interfaces. 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 TMP103 on the bus.
Up to eight TMP103s can be tied together in parallel
and easily read by the host. The TMP103 is
especially suitable for space-constrained, power-
sensitive applications with multiple temperature
measurement zones that must be monitored.
The TMP103 is specified for operation over a
temperature range of –40°C to 125°C.
