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
Table 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 ADC082S021. 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 the device.
These bits determine which input channel will be sampled and converted in
the next track/hold cycle. The mapping between codes and channels is
