High- performance 5.1ch electronic volume

BD3814FV

BD3814FV is a sound processor IC. This IC incorporates volume, bass and treble functions into a single chip that are

necessary for AV receivers and mini-component stereos.

Low distortion, low noise and wide dynamic range can be achieved by using the Bi-CMOS process.

!Features

1) Dynamic range : 132dB (Tone by-pass, VOL=MUTE, IHF-A)

2) Master volume is 6ch-Independent volume (0~95dB, Mute, 1dB/Step).

Low residual noise with Resistor ladder volume and the shock sound

in changing is reducing.

3) It is becoming a low consumption electric current design by using

the Bi-CMOS process.
