DESCRIPTION
The TMP105 is a two-wire, serial output temperature
sensor available in a WCSP package. Requiring no
external components, the TMP105 is capable of reading
temperatures with a resolution of 0.0625°C.
The TMP105 features a Two-Wire interface that is
SMBus-compatible, with the TMP105 allowing up to two
devices on one bus. The TMP105 features an SMBus Alert
function.
The TMP105 is ideal for extended temperature
measurement in a variety of communication, computer,
consumer, environmental, industrial, and instrumentation
applications.
The TMP105 is specified for operation over a temperature
range of −40°C to +125°C.
