Data Sheet
An A/D Converter Stage responsible for the analog-to-digital conversion including an
input multiplexer to select between the channel amplifiers
A Data Reduction Unit containing programmable anti-aliasing and data reduction
filters
A Channel Trigger Control block determining the trigger and gating conditions for the
FADC channels
A Channel Timer for each channel to independently trigger the conversions
An A/D Control block responsible for the overall FADC functionality

V
A differential analog input stage for each input channel to select the input impedance
(differential or single-ended measurement) and to decouple the FADC input signal
from the pins.
A channel amplifier for each input channel with a settling time (about 5µs) when
changing the characteristics of an input stage (changing between unused,
differential, single-ended N, or single-ended P mode).
