MAX5408–MAX5411
The digital output, DOUT, lags the digital input signal,
DIN by 8.5 clock cycles. Force
CS high to disable
DOUT, placing DOUT in three-state mode. Force
CS
low to enable DOUT and disable three-state mode.
Force
CS high, after a word has been written to the
MAX5408–MAX5411 to make a readback request. The
next
CS low period writes the requested data to DOUT.
A readback request overwrites any previous data in the
shift register. Note that the data appears at DOUT in
the order: A0, A1, A2, D4, D3, D2, D1, D0. A0 will be
available after the first high-to-low transition of SCLK
when
CS is low. The input continues to load the shift
register while data is being read out of the MAX5408–
MAX5411. The input data appears at DOUT 8.5 clock
cycles later. A
CS transition from low-to-high latches
the input data. For any control byte, the state of SCLK
must be the same for both
CS low-to-high transitions
and
CS high-to-low transitions in order to preserve the
data at DOUT while
CS transitions. For proper opera-
tion, ensure that the input data remains valid on both
the SCLK rising and falling edges when daisy chaining
multiple devices.
Zero-Crossing Detection
The zero-crossing detection register enables the zero-
crossing detect feature. The zero-crossing detect fea-
ture reduces the audible noise (“clicks and pops”) that
result from wiper transitions. The wiper changes posi-
tion only when the voltage at L_ is the same as the volt-
age at H_. Each wiper has a zero-crossing and timeout
