Introduction

The BD3813KS and BD3815KS sound processors integrate a gain amp and volume/bass/treble controls on a single chip, making them optimally suited for use in audio applications, such as AV receivers, home theater systems and mini-component systems. Used in combination with the BD3812F, a 2ch volume IC, the units enable 6.1ch and 7.1ch operation. In addition, utilization of a BiCMOS process ensures a wide dynamic range (129dB).

Features

Wide dynamic range: 129dB (Tone Bypass, VOL = MUTE, IHF - A)
Independent 6 channels for Master Volume (0 to -95 dB, MUTE 1dB/Step). Implementation of a resistance ladder type circuit reduces residual noise and shock sounds during switching.
Low current consumption achieved through utilization of BiCMOS processes
Maximum output voltage: 4.2Vrms (Vcc = 7V, VEE ≈ -7V, RL = 10kΩ)
Built - in 5ch independent input gain amplifier - useful for amplifying input signals
Built - in 2ch output port
2 - wire serial control (for both 3.3V and 5V)
