Product Description
The ADT7485A is a temperature- and voltage-monitoring
device. The ADT7485A can monitor the temperature of one
remote sensor diode, plus its own internal temperature. It can
also monitor up to five voltage channels, including its own
supply voltage.
SST Interface
SST is a one-wire serial bus and a communications
protocol between components intended for use in personal
computers, personal hand-held devices, or other industrial
sensor nets. The ADT7485A supports SST Rev 1.0.
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 B724.
ADT7485A Client Address
The client address for the ADT7485A is selected using the
address pin. The address pin is connected to a float detection
circuit, which allows the ADT7485A to distinguish between
three input states: high, low (GND), and floating. The
address range for the fixed address, discoverable device is
0x48 to 0x4A.

Command Summary
Table 6 summarizes the commands supported by the
ADT7485A device when directed at the target address
selected by the fixed address pin. It contains the command
name, command code (CC), write data length (WL), read
data length (RL), and a brief description.

Command Code Details
ADT7485A Device Identifier Block
The GetDIB() command retrieves the device identifier
block (DIB), which provides information to identify the
capabilities of the ADT7485A. The data returned can be in
8- or 16-byte format. The full 16 bytes of DIB is detailed in
Table 7. The 8-byte format involves the first eight bytes
described in this table. Byte-sized data is returned in the
respective fields as it appears in Table 7. Word-sized data,
including vendor ID, device ID, and data values use little
endian format, that is, the LSB is returned first, followed by
the MSB.
