20.7.3
The configuration for 600 ksps operation is dependent
on whether a single input pin is to be sampled or
whether multiple pins will be sampled.
20.7.3.1
When performing conversions at 600 ksps for a single
analog input, at least two sample and hold channels
must be enabled. The analog input multiplexer must be
configured so that the same input pin is connected to
both sample and hold channels. The A/D converts the
value held on one S/H channel, while the second S/H
channel acquires a new input sample.
20.7.3.2
The A/D converter can also be used to sample multiple
analog inputs using multiple sample and hold channels.
In this case, the total 600 ksps conversion rate is
divided among the different input signals. For example,
four inputs can be sampled at a rate of 150 ksps for
each signal or two inputs can be sampled at a rate of
300 ksps for each signal. Sequential sampling must be
used in this configuration to allow adequate sampling
time on each input.
20.7.3.3
The following configuration items are required to
achieve a 600 ksps conversion rate.
• Comply with conditions provided in Table 20-2
