Temperature Data Format
One LSB of the ADC corresponds to 0.125
°C, so the
ADM1023 can measure from 0
°C to 127.875°C. The
temperature data
format
and
extended
temperature
resolution are shown in Table 1 and Table 2.

1. The ADM1023 differs from the ADM1021 in that the
temperature resolution of the remote channel is improved
from 1
°C to 0.125°C, but it cannot measure temperatures
below 0
°C. If negative temperature measurement is required,
the ADM1021 should be used.
The results of the local and remote temperature
measurements are stored in the local and remote temperature
value registers and are compared with limits programmed
into the local and remote high and low limit registers.

Register Functions
The ADM1023 contains registers that are used to store the
results of remote and local temperature measurements and
high and low temperature limits, and to configure and
control the device. A description of these registers follows,
and further details are given in Table 3 to Table 7. Most of
the registers for the ADM1023 are dual−port and have
different addresses for read and write operations.
Attempting to write to a read address or to read from a write
address produces an invalid result. Register addresses above
0x14 are reserved for future use or factory test purposes and
should not be written to.
Address Pointer Register
The address pointer register does not have, nor does it
require, an address, because it is the register to which the
first data byte of every write operation is automatically
written. This data byte is an address pointer that sets up one
of the other registers for the second byte of the write
operation or for a subsequent read operation.
Value Registers
The ADM1023 has three registers to store the results of
local and remote temperature measurements. These
registers are written to by the ADC and can only be read over
the SMBus.
The Offset Register
Two offset registers are provided at Address 0x11 and
Address 0x12. These are provided so that the user may
remove errors from the measured values of remote
temperature. These errors may be introduced by clock noise
and PCB track resistance. See Table 4 for an example of
offset values.
The offset value is stored as an 11−bit, twos complement
value in Register 0x11 (high byte) and Register 0x12 (low
byte, left justified). The value of the offset is negative if the
MSB of Register 0x11 is 1, and it is positive if the MSB of
Register 0x11 is 0. This value is added to the remote
temperature. These registers default to 0 at powerup and
have no effect if nothing is written to them. The offset
register can accept values from −128.875
°C to +127.875°C.
The ADM1023 detects overflow so the remote temperature
value register does not wrap around +127
°C or −128°C.
