Spectral analysis band-pass filter for mini component stereo
BA3833F
The BA3833F is a 4+1 band-pass filter IC for spectrum analyzer with built-in recording indicator output. External components can be reduced largely by incorporating all capacitors that compose a filter. This enables to make set smaller and more highly-reliable.
Applications CD radio cassette player, mini component stereo, car stereo
External dimensions (Unit : mm)
11.20.2
Features 1) Spectral analysis 4-band band-pass filter and rectifier circuit (with internal capacitor). 2) Detector circuit for every frequency. 3) Parallel output with internal Lch / Rch mixing-up function. 4) Single battery operation in 5 to 6 V.
