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.
