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.

Features include:
  • CUSTOMER SPECIFIED FREQUENCY
    Your choice of -3 dB Frequency.
    Customer modifications available at
    No additional charge.
  • EXTREMELY SMALL.
    0.45" L x 0.47" W x 0.40" H (8 pins)
