• TINY SOT563 PACKAGE

The TMP112 is a two-wire, serial output temperature

sensor available in a tiny SOT563 package. Requiring

• ACCURACY:

no external components, the TMP112 is capable of

0.5°C (max) from 0°C to +65°C

reading temperatures to a resolution of 0.0625°C.

1.0°C (max) from –40°C to +125°C

The TMP112 slope-specification allows users to

• LOW QUIESCENT CURRENT:

calibrate for higher accuracy.
