uS5004
Digital Remote and Local Temperature Sensor
with SMBus Serial Interface
Features
General Description
Remote and Local Temperature Measurements
Do Not Need to Calibrate
The uS5004 is a digital thermometer to monitor both remote
and local temperature, it accurately measures its own
temperature and the remote temperature that mounted
2N3904 diode-connected transistor that can replace
conventional thermistors and thermocouples.

The standard 2-wire interface System Management Bus
(SMBus) accepts Write byte, Read byte, Send byte, and
Receive byte command to communicate with uS5004. The
device data format of remote temperature measurement is
11bits, with each bit of the extended 3bits corresponding
0.125OC.
