MINIATURE FILTERS
Fixed Analog Active
Filters
Anti-Aliasing - AS
Series
Valuable board space can now be
saved by AS series miniature filter
module. User is able to maximize
system bandwidth, minimize
sampling rate and still obtain anti-
aliasing attenuation greater than 80
dB at 2 times of the cut-off in a 16
pin DIP package.
