DESCRIPTION

The TMP100 and TMP101 are 2-wire, serial output tempera-

ture 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.

face compatibility, with the TMP100 allowing up to eight

devices on one bus. The TMP101 offers SMBus alert func-

tion with up to three devices per bus.

The TMP100 and TMP101 are ideal for extended tempera-

ture 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.
