AD5384
Data Sheet
INTERFACES
The AD5384 contains a serial interface that can be
programmed as DSP-, SPI-, MICROWIRE-, or I2C-compatible.
Select DSP, SPI, MICROWIRE, or I2C interface mode by using
the SPI/I2C pin . To minimize both the power consumption of
the device and the on-chip digital noise, the active interface
powers up fully only when the device is being written to on the
falling edge of SYNC.
DSP-, SPI-, MICROWIRE-COMPATIBLE SERIAL
INTERFACE
The serial interface operates with a minimum of three wires in
standalone mode or five wires in daisy-chain mode. Daisy-
chaining allows many devices to be cascaded together to
increase system channel count. Tie the SPI/I2C (Ball B8) high to
enable the DSP-, SPI-, or MICROWIRE-compatible serial
interface. The following are the serial interface control pins:
SYNC/AD0, DIN/SDA, and SCLK/SCL are the standard
3-wire interface pins.
DCEN/AD1 selects standalone mode or daisy-chain
mode.
SDO is the data out pin for daisy-chain mode.
Figure 3 and Figure 5 show the timing diagrams for a serial
write to the AD5384 in standalone and in daisy-chain modes.
The 24-bit data-word format for the serial interface is shown in
Table 15. The bit descriptions are as follows:
When toggle mode is enabled, the A/B bit selects
whether the data write is to the A register or B register.
When toggle mode is disabled, set A/B to zero to select
the A data register.
R/W is the read or write control bit.
A5 to A0 are used to address the input channels.
REG1 and REG0 select the register to which data is
written, as shown in Table 7.
DB13 to DB0 contain the input data-word.
X is a don’t care condition.
Standalone Mode
Connect the DCEN (daisy-chain enable) pin low to enable
standalone mode. The serial interface works with both a
continuous and a noncontinuous serial clock. The first falling
edge of SYNC starts the write cycle and resets a counter that
counts the number of serial clocks to ensure that the correct
number of bits are shifted into the serial shift register. Any
further edges on SYNC, except for a falling edge, are ignored
until 24 bits are clocked in. Once 24 bits are shifted in, SCLK is
ignored. For another serial transfer to take place, reset the
counter by the falling edge of SYNC.
