Applications Information
(Continued)
conversion, it is necessary to clock in the data indicating the
input that is selected for the conversion after the current one.
See Tables 1, 2 and 3.
If CS and SCLK go low simultaneously, it is the following
rising edge of SCLK that is considered the first rising edge
for clocking data into DIN.
There are no power-up delays or dummy conversions re-
quired with the ADC124S021. The ADC is able to sample
and convert an input to full conversion immediately following
power up. The first conversion result after power-up will be
that of IN1.

Description
Don’t care. The value of these bits do not affect device operation.
These three bits determine which input channel will be sampled and
converted in the next track/hold cycle. The mapping between codes and
channels is shown in
