Overview
Sound processor for DVD player BD3824FS Description BD3824FS is a single chip IC for DVD recorder application.
Each function of 5-channel input selector, input gain, tuner gain, ALC, line amplifier and power save ON/OFF can be controlled by I2C BUS.

1 16 1) Low distortion rate and low noise 0.
8 2) Built-in ALC circuit can be used as RF output 3) Perfect for low current consumption and energy saving design due to BiCMOS process 4) SSOP-A32 package.
Layout terminals for audio input and audio output are located together to arrange the flow of signal in the same direction enabling an easy pattern layout and saving space on the board.
5) Same PCB board as BD3822FS is available.
I2C BUS software of BD3822FS can be used without any modification.
6) Original system is applied, which its input (tuner, FRONT, EXT) waveform is not distorted at I2C BUS standby mode.
