1600 Series - 255 step Programmable Filter Modules

We now keep a range of 'standard' filter modules in stock, covering a wide frequency and application range.
24 dB/Octave and 48 dB/Octave Butterworth
24 dB/Octave and 48 dB/Octave Bessel
Anti Aliasing  >-80 dB at 1.5 cut off frequency
Linear Phase, flat to cut off,  >-80 dB at 3 times cut off
Most of the above are available to cover cut off frequencies from 0.1 Hz to 500 kHz from stock

  • Lowpass   Highpass  Notch
  • 0.1 Hz to > 500 kHz
  • Butterworth, Bessel, Linear phase, and anti-aliasing
  • Stable DC characteristics
  • Typically > 80dB rejection (1:104)
  • Low distortion
  • 255 step programmable ( 8 bit )
  • Many types held in stock
  • High quality continuous filters-no switching frequencies!

1600 Programable signal filter module


The Kemo range of programmable filter modules are manufactured using parts from the 1200 Series, stocks of 1600 modules reflect the types held for the 1200 series.
With digitally settable cutoff frequency over a 255:1 span, this is the finest board-mounting active filter solution available today. Cutoff goes as low as 0.2Hz and as high as 255kHz. Lowpass, and highpass,  responses suitable for anti-aliasing and general purpose filtering held in stock. Wide dynamic range, low distortion and noise (true 16bit performance can be achieved with many models). Small size: eight pole models provide industrial-strength filtering in a 50 x 50 x 15mm (2"x2"x0.6") metal box.

We work hard to keep filter modules with the following filter responses

Butterworth 24 dB/ Octave Response 03
Butterworth 48 dB/ Octave Response 05
Bessel 24 dB/ Octave Response 07
Bessel 48 dB/ Octave Response 09
Anti-aliasing Response 01
General Purpose
response 41
Sharp Notch (Q=10) NQ10

 With the frequency ranges listed above as lowpass filters in stock, or available for fast delivery.
Some of the more popular frequencies and filter responses are available as highpass filters.
Most other combinations are available to special order. Due to the stocks of components we have, and the flexible manufacturing methods used, we can usually supply small numbers of special order filters within a few working days.

1600W series
Extended cutoff frequency span of 1792:1 instead of 255:1. Pin-compatible with 1600 in most applications. 
Available in the standard filter responses.
Fits all Kemo carrier cards, including 6UG/1600
1600W now has its own page.

Support for older Filter Modules

A note for long-standing users of our modules: we try to provide the highest level of support for all our customers and for service needs we can recreate many of the modular products we have produced in the last three decades. Also contact us for advice on replacing products from defunct suppliers.
