Sound processor for car audio

BD3801FS

●Description

The BD3801FS is a sound processor IC for car audio

applications. High S/N and low distortion parametric

equalizer can be constructed without external capacitor

by high-performance switched capacitor filter technology.

Soft switch can reduce pop noise at switching volume.

1）Slice the external parts by using switched capacitor circuit.

2）Reduce the noise of through mode by using tone-pass route.

(8μVrms)

3）Possible to realize paramentric equalizer using 3 band tone,

and 2 band tone and loudness.

4）Built-in ground isolation amplifiter input, ideal for external stereo

input and monaural input. (1 stereo input and 2 monaural input)

5）It is using a I2C BUS control. Because it is possible to use at the

same time in a maximum of two.

6）BiCMOS process is suitable for the design of low current

(Typ.10mA) and low energy.
