BD3805F
The BD3805F is a sound processor developed for car audio. High S/N and low distortion rate of parametric equalizer can
be composed without an external capacitor. Pop noise when switching volume, fader, mute and tone gain can’t be heard
due to the integrated soft switching circuit.
zApplications
Car audio, Mini component stereo, Micro component stereo, DVD, TV
zFeatures
zExternal dimensions (Unit : mm)
1) Noise when switching, attenuation of fader and fader, and gain
(middle bass and treble) can be reduced by soft switching circuit..
2) Perfect due low current consumption (Typ.12mA) and energy saving
design due to Bi-CMOS process.
3) Available for Rear Entertainment System due to I2C BUS control

that can use two ICs at maximum.
4) Noise occurred through tone pass can be reduced (5µ Vrms)
5) External components reduced largely by incorpDoarattainSgheexteetr4naUl .ficltoerm
due to the switched capacitor circuit technology.

Bass, treble and middle can be controlled freely.
6) Integrated Ground Isolation Amplifier input idea for external stereo
signal input.

7) SOP22 package is adopted Pins for voice input and signal output
are located together to arrange the flow of signal in a same direction.
It enables to make layout of board pattern easier and to save space
of the board.
