Band-pass filter for spectral analyzers

BA3830S

The BA3830S is a 61 band band-pass filter for spectral analyzer displays with internal recording indicator output. All
of the capacitors comprising the filter are internal capacitors, making it possible to significantly reduce the number of
attached components. This enables configuration of compact sets with a high level of reliability .

Applications
CD radio cassette players, mini-components, car stereos

Features

1) Six internal band-pass filters for spectral analyzers

2) Internal input/output for recording indicators

Absolute maximum ratings (Ta = 25C)

3) Internal capacitors reduce the number of attach­ments.

Recommended operating conditions (Ta = 25C)
