multiplexing is selected, none of the MA[2:0] pins can be used for analog or digital
inputs. They become multiplexed address outputs.
The number of available analog channels varies, depending on whether or not external
multiplexing is used. A maximum of 16 analog channels are supported by the internal
multiplexing circuitry of the converter.
input channels supported with zero-to-four external multiplexers.
The QADC64 analog subsystem includes a front-end analog multiplexer, a digital-to-
analog converter (DAC) array, a comparator, and a successive approximation register
(SAR).
The analog subsystem path runs from the input pins through the input multiplexing cir-
cuitry, into the DAC array, and through the analog comparator. The output of the
comparator feeds into the SAR.
