Description
The BD3860K is a sound processor IC for car audio
applications.
This IC provides treble clarity through the bass field
incorporating
function.
R
This IC has clarity without increasing volume levels
which makes it suitable for car stereo sound systems.
Dimension (Units : mm)
Features
1) Incorporates
R , 4-input selector (4-channel
stereo), input gain, main volume, loudness, tone
(2-band), fader volume.
2) Resistor ladder volume allows low distortion and low
noise through the Bi-CMOS process.
3) 2-wire serial control.
4) Available in and QFP44 package, ideal for compact
designs.
Applications
Car stereos, Mini component stereos, Micro component stereos
