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.
The TMP100 and TMP101 feature SMBus and I²C™ inter-
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.
