5.2 Multi-Buffered 12-bit Analog-to-Digital Converter
The multibuffered A-to-D converter (MibADC) has a separate power bus for its analog circuitry that
enhances the A-to-D performance by preventing digital switching noise on the logic circuitry which could
be present on V
SS
and V
CC
from coupling into the A-to-D analog stage. All A-to-D specifications are given
with respect to AD
REFLO
unless otherwise noted.
