Sound Processors for Home Theater Systems

5.1ch

Sound Processors

BD3813KS,BD3815KS

No.10081EAT04

●Description

The BD3813KS and BD3815KS sound processors integrate a gain amp and volume/bass/treble controls on a single chip,

making them optimally suited for use in audio applications, such as AV receivers, home theater systems and mini-component

systems. Used in combination with the BD3812F, a 2ch volume IC, the units enable 6.1ch and 7.1ch operation.

In addition, utilization of a BiCMOS process ensures a wide dynamic range (129dB).

●Features

1) Wide dynamic range: 129dB (Tone Bypass, VOL=MUTE, IHF-A)

2) Independent 6 channels for Master Volume (0 to -95 dB, MUTE 1dB/Step)

Implementation of a resistance ladder type circuit reduces residual noise and shock sounds during switching.

3) Low current consumption achieved through utilization of BiCMOS processes

4) Maximum output voltage: 4.2Vrms (Vcc=7V, VEE=-7V, RL=10kΩ)

5) Built-in 5ch independent input gain amplifier - useful for amplifying input signals

6) Built-in 2ch output port

7) 2-wire serial control (for both 3.3V and 5V)

●Applications

AV receivers, home theater systems and mini-component systems

●Line up matrix
