INPUT SHIFT REGISTER
The input shift register is 24 bits wide (see Figure 34). The first
six bits are don’t cares. The next two are control bits that control
the part’s mode of operation (normal mode or any one of three
power-down modes). See the Power-Down Modes section for a
more complete description of the various modes. The next 16
bits are the data bits. These are transferred to the DAC register
on the 24th falling edge of SCLK.
SYNC INTERRUPT
In a normal write sequence, the SYNC line is kept low for at
least 24 falling edges of SCLK, and the DAC is updated on the
24th falling edge. However, if SYNC is brought high before the
24th falling edge, this acts as an interrupt to the write sequence.
The shift register is reset and the write sequence is seen as
invalid. Neither an update of the DAC register contents nor a
change in the operating mode occurs (see
).
POWER-ON RESET
The AD5662 family contains a power-on reset circuit that
controls the output voltage during power-up. The AD5662x-1
DAC output powers up to 0 V, and the AD5662x-2 DAC output
powers up to midscale. The output remains there until a valid
write sequence is made to the DAC. This is useful in
applications where it is important to know the state of the
output of the DAC while it is in the process of powering up.
