BA3833F Audio ICs 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. zApplications CD radio cassette player, mini component stereo, car stereo zExternal dimensions (Unit : mm) 11.2±0.2 18 10 1 9 1.27 0.15±0.1 4.4±0.2 7.8±0.3 1.8±0.1 0.11 zFeatures 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. 0.4±0.1 0.3Min. 0.15 SOP18 zAbsolute maximum ratings (Ta=25°C) Symbol Limits Supply voltage Parameter VCC 9 Power dissipation Pd Unit V 550 ∗ mW Operating temperature range Topr −40 to +85 C Storage temperature range Tstg −55 to +125 C ∗ For an operation with Ta=25 C or more, 5.5mW shall be reduced per 1 C.
