●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.

●Features
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.

●Applications
Car stereo, Mini component stereo, Micro component stereo, DVD, Personal computer, TV.
