Sound Processor
BD3811K1,BD3818KS
No.10081EAT02
Description
BD3811K1 and BD3818KS are 5.1ch sound processors, with built-in Mode Selector/Input Selector. Functions, including
6-ch Volume, Gain Amp, Bass, Treble, Mixing (BD3818KS), Dynamic Bass Boost (BD3818KS) and Bass Boost (BD3811K1)
are integrated into a single chip.
Features
1) Independent 6 channels for Master Volume (0 to -103dB, 1dB/Step, MUTE, BD3811K1)
(0 to -95dB 1dB/Step, MUTE, BD3818KS)
Implementation of a resistance ladder type circuit reduces residual noise and a shock sound at switching.
2) Low current consumption design achieved by adopting the BiCMOS process
3) Maximum output voltage (BD3818KS): 4.3Vrms (Vcc=7V, VEE=-7V, RL=10k)
Maximum output voltage (BD3811K1): 4.2Vrms (Vcc=7V, VEE=-7V, RL=10k)
4) Built-in Input Gain Amp useful for adjusting the output signal voltages
5) Built-in Operational Amplifier useful for filter construction (BD3818KS)
6) Built-in Dynamic Bass Boost circuit (BD3818KS)
7) 2-wire serial control (BD3818KS for 5V, BD3811K1 for both 3.3V and 5V)
8) Built-in Output Gain Amp useful for adjusting the output signal voltages (BD3811K1)
9) REC output terminal with a REC input/output switch useful for monitoring Equalizer Amp (BD3811K1)
10) Output mute controlled by either serial data or an external control terminal
Applications
AV receivers, home theater systems and mini-audio systems.

Timing chart
1. Signal Timing Conditions
Data is read on the rising edge of the clock.
Latch is read on the falling edge of the clock.
Latch signal must terminate with the LOW state.
* To avoid malfunctions, clock and data signals must terminate with the LOW state.
