DESCRIPTION
The TMP175 and TMP75 are two-wire, serial output
temperature sensors available in SO-8 and MSOP-8
packages. Requiring no external components, the
TMP175 and TMP75 are capable of reading temperatures
with a resolution of 0.0625°C.
The TMP175 and TMP75 feature a Two-Wire interface that
is SMBus-compatible, with the TMP175 allowing up to 27
devices on one bus and the TMP75 allowing up to eight
devices on one bus. The TMP175 and TMP75 both feature
an SMBus Alert function.
The TMP175 and TMP75 are ideal for extended
temperature measurement in a variety of communication,
computer, consumer, environmental, industrial, and
instrumentation applications.
The TMP175 and TMP75 are specified for operation over
a temperature range of −40°C to +125°C.
