When CS is low (MAX4822/MAX4823 device is select-
ed), data at DIN is clocked into the shift register syn-
chronously with SCLK’s rising edge. Driving CS from
low to high latches the data in the shift register (Figures
5 and 6).

DOUT is the output of the shift register. Data appears
on DOUT synchronously with SCLK’s falling edge and
is identical to the data at DIN delayed by eight clock
cycles for the MAX4823, or 16 clock cycles for the
MAX4822. When shifting the input data, A7 is the first
input bit in and out of the shift register for the MAX4822
device. D7 is the first bit in or out of the shift register for
