Preliminary Technical Data
ADT7485
Rev. PrA | Page 9 of 16
PRODUCT DESCRIPTION
The ADT7485 is a temperature and voltage monitoring device.
The ADT7485 can monitor the temperature of one remote sensor
diode, plus its own internal temperature. It can also monitor up
to five voltage channels, including it’s own supply voltage.
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 ADT7485 supports SST Rev 0.9.
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, Inc., at sst_licensing@analog.com
or write to Analog Devices, Inc., 3550 North First Street, San
Jose, CA 95134, Attention: SST Licensing, M/S B7-24.
The client address for the ADT7485 is selected using the
address pin. The address pin is connected to a float detection
circuit, which allows the ADT7485 to distinguish between three
input states: high, low (GND), and floating. The address range
for fixed address, discoverable devices is 0x54 to 0x56.
