BD3818KS

Sound Processors for Home Theater Systems 5.1ch 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=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. ●Line up matrix Parameter Input Selector Input Gain ...
