DESCRIPTION
The TMP112 is a two-wire, serial output temperature
sensor available in a tiny SOT563 package. Requiring
no external components, the TMP112 is capable of
reading temperatures to a resolution of 0.0625°C.
The TMP112 slope-specification allows users to
calibrate for higher accuracy.
The TMP112 features both SMBus and two-wire
interface compatibility, and allows up to four devices
on one bus. It also features an SMBus alert function.
The TMP112 is ideal for extended temperature
measurement in communication, computer,
consumer, environmental, industrial, and
instrumentation applications. It is specified for
operation over a temperature range of –40°C to
+125°C.
