Description

The 428H4B are 8-pole digitally programmable low-pass and high-pass active filters.  These new filters 428H4B take advantage of the company's proprietary designs using surface-mount technology to provide a low profile, compact package in minimal board space.  428H4B filters are factory tuned to one of ten preset 4-bit binary ranges from 10 Hz to 102.4 kHz. Contact  the  factory  for  custom  discrete  tuning ranges, maximum span 1000:1.

428H4B models are easy to use fully finished filters  which  require  no  external  components  or adjustment. 428H4B feature low harmonic distortion, near theoretical phase and amplitude characteristics and  operate  over  a  dynamic  input  voltage  range from non-critical ±12V to ±18V power supplies.
