Digital Temperature Sensor
with Two-Wire Interface
FEATURES
DESCRIPTION
The TMP175 and TMP75 are Two-Wire, serial output tem-
27 ADDRESSES (TMP175)
8 ADDRESSES (TMP75)
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.
DIGITAL OUTPUT: Two-Wire Serial Interface
RESOLUTION: 9- to 12-Bits, User-Selectable
ACCURACY: ±1.5°C (max) from –25°C to +85°C
±2.0°C (max) from –40°C to +125°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.
LOW QUIESCENT CURRENT: 50µA, 0.1µA Standby
WIDE SUPPLY RANGE: 2.7V to 5.5V
The TMP175 and TMP75 are ideal for extended temperature
measurement in a variety of communication, computer, con-
sumer, environmental, industrial, and instrumentation appli-
cations.
SMALL SO-8 PACKAGE
The TMP175 and TMP75 are specified for operation over a
temperature range of –40°C to +125°C.
