6.1 ADC Operation
ADC functions can be grouped into three basic subsystems: an analog front end, a digital control sec-
tion, and a bus interface. A block diagram of the converter follows.

6.2 Analog Subsystem
The analog front end consists of a multiplexer, a buffer amplifier, a resistor-capacitor array, and a high-
gain comparator. The multiplexer selects one of eight internal or eight external signal sources for con-
version. The buffer amplifier protects the input channel from the relatively large capacitance of the RC
array. The resistor capacitor (RC) array performs two functions — it acts as a sample/hold circuit, and
it provides the digital-to-analog comparison output necessary for successive approximation conversion.
The comparator indicates whether each successive output of the RC array is higher or lower than the
sampled input.
