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.
FApplications
CD radio cassette players, mini-components, car stereos
FFeatures
1) Six internal band-pass filters for spectral analyzers
2) Internal input / output for recording indicators
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)
Band-pass filter for spectral analyzers
BA3830S
Audio ICs
3) Internal capacitors reduce the number of attach-
ments.

... This is a circuit that selects the required frequency com- ponent from the input signal and amplifies it. With this configuration, no external capacitor is needed. In addi- tion, the center frequency is set based on the current and can be set individually, using separate ex ternal resistors (pins1 and 2 set to 4.5V (Typ.). BA3830S 587 ...

... conversion and is output. Since the next stage sup- ports MOS (high-input impedance), there is a resistance of 33.9k (44.3k for REC output only) between the out- put pin and the GND in the IC, so the output value changes based on the input impedance. 588 BA3830S ...
