which is the power-on default, the device is in operating
mode with the ADC converting (see Table 10). If Bit 6 is set
to 1, the device is in standby mode and the ADC does not
convert. Standby mode can also be selected by taking the
STBY pin low. In standby mode, the values of remote and
local temperature remain at the value they were before the
part was placed in standby mode.
Bit 7 of the configuration register is used to mask the
ALERT output. If Bit 7 is 0, which is the power-on default,
the ALERT output is enabled. If Bit 7 is set to 1, the ALERT
output is disabled.

Limit Registers
The ADM1023 has six limit registers to store local and
remote, high and low temperature limits. These registers can
be written to and read back over the SMBus. The high limit
registers perform a > comparison, while the low limit
registers perform a < comparison. For example, if the high
limit register is programmed as a limit of 80 ? C, measuring
81 ? C results in an alarm condition. Even though the
temperature range is 0 to 127 ? C, it is possible to program the
limit register with negative values. This is for
backward-compatibility with the ADM1021.

and comparison cycle when the ADM1023 is in standby
mode, after which the device returns to standby. This is not
a data register as such, and it is the write operation that
causes the one-shot conversion. The data written to this
address is irrelevant and is not stored.
Serial Bus Interface
Control of the ADM1023 is carried out via the serial bus.
Conversion Rate Register
The lowest three bits of this register are used to program
the conversion rate by dividing the ADC clock by 1, 2, 4, 8,
16, 32, 64, or 128, to give conversion times from 125 ms
(Code 0x07) to 16 seconds (Code 0x00). This register can be
written to and read back over the SMBus. The higher five
bits of this register are unused and must be set to 0. Use of
slower conversion times greatly reduces the device’s power
consumption, as shown in Table 11.
The ADM1023 is connected to this bus as a slave device,
under the control of a master device. Note that the SMBus
SDA and SCLK pins are three-stated when the ADM1023
is powered down, and they do not pull down the SMBus.
Address Pins
In general, every SMBus device has a 7-bit device address
(except for some devices that have extended, 10-bit
addresses). When the master device sends a device address
over the bus, the slave device with that address responds.
The ADM1023 has two address pins, ADD0 and ADD1, to
allow selection of the device address, so that several
ADM1023s can be used on the same bus and to avoid
conflict with other devices. Although only two address pins
are provided, these pins are three-state and can be grounded,
left unconnected, or tied to V DD , so that a total of nine
different addresses are possible, as shown in Table 12.
Note that the state of the address pins is sampled only at
powerup, so changing them after powerup has no effect.
