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.
