The CS501X family of A/D converters have
within their capacitor-based architecture a trackand-
hold function. Upon completing a conversion
the A/D converter immediately begins to track
the input signal. The design is such that the input
signal is buffered (internal to the A/D) from
the capacitor array for six cycles of the master
clock. Then the buffer is bypassed and the array
is directly connected to the AIN pin of the converter.
This allows the converter to settle to its
final value within the accuracy specifications.
The period of time that the buffer is connected is
known as the coarse charge time.
