3 Description
The TMP104 device is a digital output temperature
sensor in a four-ball wafer chip-scale package
(WCSP). The TMP104 is capable of reading
temperatures to a resolution of 1°C.
The TMP104 features a SMAART wire™ interface
that supports daisy-chain configurations. In addition,
the interface supports multiple device access (MDA)
commands that allow the master to communicate with
multiple devices on the bus simultaneously,
eliminating the need to send individual commands to
each TMP104 on the bus.
Up to 16 TMP104s can be tied together in parallel
and easily read by the host. The TMP104 is
especially ideal for space-constrained, powersensitive
applications with multiple temperature
measurement zones that must be monitored.
The TMP104 is specified for operation over a
temperature range of –40°C to +125°C.
