with all zeros. This means that if the user clears the part after
power-up, the output is actively driven to 0 V (if the channel
has been enabled for clear).
After a device power on, or a device reset, it is recommended to
wait 100 μs or more before writing to the device to allow time
for internal calibrations to take place.
SERIAL INTERFACE
The AD5755-1 is controlled over a versatile 3-wire serial
interface that operates at clock rates of up to 30 MHz and is
compatible with SPI, QSPI, MICROWIRE, and DSP standards.
Data coding is always straight binary.
Input Shift Register
The input shift register is 24 bits wide. Data is loaded into the
device MSB first as a 24-bit word under the control of a serial
clock input, SCLK. Data is clocked in on the falling edge of SCLK.
If packet error checking, or PEC (see the Device Features
section), is enabled, an additional eight bits must be written to
the AD5755-1, creating a 32-bit serial interface.
There are two ways in which the DAC outputs can be updated:
individual updating or simultaneous updating of all DACs.
Individual DAC Updating
In this mode, LDAC is held low while data is being clocked into
the DAC data register. The addressed DAC output is updated on
the rising edge of SYNC. See Table 3 and Figure 3 for timing
information.
Simultaneous Updating of All DACs
In this mode, LDAC is held high while data is being clocked
into the DAC data register. Only the first write to each channel’s
DAC data register is valid after LDAC is brought high. Any subse-
quent writes while LDAC is still held high are ignored, though
they are loaded into the DAC data register. All the DAC outputs
are updated by taking LDAC low after SYNC is taken high.
