DESCRIPTION
The TMP275 is a 0.5°C accurate, two-wire, serial output
temperature sensor available in the MSOP-8 package. The
TMP275 is capable of reading temperatures with a resolution
of 0.0625°C.
The TMP275 is SMBus-compatible and allows up to eight
devices on one bus. It is ideal for extended temperature
measurement in a variety of communication, computer,
consumer, environmental, industrial, and instrumentation
applications.
The TMP275 is specified for operation over a temperature
range of −40°C to +125°C.
