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.

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.
