Digital Temperature Sensor
with I2C
Interface
DESCRIPTION
The TMP100 and TMP101 are two-wire, serial output
temperature sensors available in SOT23-6 packages.
Requiring no external components, the TMP100 and
TMP101 are capable of reading temperatures with a
resolution of 0.0625°C.
The TMP100 and TMP101 feature SMBus and I2C
interface compatibility, with the TMP100 allowing up to
eight devices on one bus. The TMP101 offers SMBus alert
function with up to three devices per bus.
The TMP100 and TMP101 are ideal for extended
temperature measurement in a variety of communication,
computer, consumer, environmental, industrial, and
instrumentation applications.
The TMP100 and TMP101 are specified for operation over
a temperature range of −55°C to +125°C.
