DESCRIPTION
The TMP100-Q1-Q1 and TMP101-Q1 are two-wire, serial output temperature sensors available in SOT23-6
packages. Requiring no external components, the TMP100-Q1-Q1 and TMP101-Q1 are capable of reading
temperatures with a resolution of 0.0625°C.
The TMP100-Q1-Q1 and TMP101-Q1 feature SMBus and I²C interface compatibility, with the TMP100-Q1
allowing up to eight devices on one bus. The TMP101-Q1 offers SMBus alert function with up to three devices
per bus.
The TMP100-Q1 and TMP101-Q1 are ideal for extended temperature measurement in a variety of
communication, computer, consumer, environmental, industrial, and instrumentation applications.
The TMP100-Q1 and TMP101-Q1 are specified for operation over a temperature range of −40°C to 125°C.
