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=10kΩ)
Maximum output voltage (BD3811K1): 4.2Vrms (Vcc=7V, VEE=-7V, RL=10kΩ)
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.
