Product details

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 ou.
