INTERFACES
The AD5390/AD5391/AD5392 contain a serial interface that
can be programmed to be DSP-, SPI-, and MICROWIRE-
compatible, or I2C-compatible. The SPI/I2C pin is used to select
the interface mode.
To minimize both the power consumption of the device and the
on-chip digital noise, the interface fully powers up only when the
device is being written to, that is, on the falling edge of SYNC.
DSP-, SPI-, AND MICROWIRE-COMPATIBLE SERIAL
INTERFACE
The serial interface can be operated with a minimum of three
wires in standalone mode or four wires in daisy-chain mode.
Daisy-chaining allows many devices to be cascaded together to
increase system channel count. The SPI/I2C pin is tied to a
Logic 1 pin to configure this mode of operation. The serial
interface control pins are described in Table 17.

Pin
Description
SYNC, DIN, SCLK
Standard 3-wire interface pins.
DCEN
Selects standalone mode or daisy-chain mode.
SDO
Data out pin for daisy-chain mode.
Figure 2 to Figure 4 show timing diagrams for a serial write to
the AD5390/AD5391/AD5392 in both standalone and daisy-
chain mode. The 24-bit data-word format for the serial interface
is shown in Table 18 to Table 20. Descriptions of the bits follow

Bit
Description
A/B
When toggle mode is enabled, this bit selects whether the data write is to the A or B register. With toggle mode disabled, this
bit should be set to zero to select the A data register.
R/W
The read or write control bit.
A3 to A0
Used to address the input channels.
REG1 and
REG0
Select the register to which data is written, as outlined in Table 10.
DB13 to
DB0
Contain the input data-word.
X
Don’t care condition.
