DESCRIPTION
The TMP175 and TMP75 are Two-Wire, serial output tem-
perature sensors available in an SO-8 package. 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, con-
sumer, environmental, industrial, and instrumentation appli-
cations.
The TMP175 and TMP75 are specified for operation over a
temperature range of –40°C to +125°C.
