Product Description
The ADT7484A is a single remote temperature sensor,
and the ADT7486A is a dual temperature sensor for use in
PC applications. The ADT7484A/ADT7486A accurately
measure local and remote temperature and communicate
over a one-wire Simple Serial Transport (SST) bus interface.
SST Interface
Simple Serial Transport (SST) is a one-wire serial bus and
a communications protocol between components intended
for use in personal computers, personal handheld devices, or
other industrial sensor nets. The ADT7484A/ADT7486A
support SST specification Rev 1.
SST is a licensable bus technology from Analog Devices,
Inc., and Intel Corporation. To inquire about obtaining a
copy of the Simple Serial Transport Specification or an SST
technology license, please email Analog Devices, at
sst_licensing@analog.com or write to Analog Devices,
3550 North First Street, San Jose, CA 95134, Attention:
SST Licensing, M/S B7-24.
ADT7484A/ADT7486A Client Address
The client address for the ADT7484A/ADT7486A is
selected using the address pin. The address pin is connected
to a float detection circuit, which allows the ADT7484A/
ADT7486A to distinguish between three input states: high,
low (GND), and floating. The address range for fixed
address, discoverable devices is 0x48 to 0x50.
