Features
1) Dynamic range: 129dB (Tone bypass,VOL=MUTE, IHF-A)
2) Independent 6-channel for master volume (0~-95dB, MUTE 1dB/Step)
Utilization of resistor rudder has dramatically reduced residual
noise as well as noise generated by switching.
3) Low consumption current design by adopting Bi-CMOS process
4) Maximum output voltage: 4.2Vrms (Vcc=7v, VEE=-7V, RL=10k )
5) Built-in 5-channel independent input gain amplifier convenient to
amplify input signal (BD3813KS: 0, 6, 12dB), (BD3815KS: 0, 6, 18dB)
6) 2-channel output port
7) 2-wire serial control (For both 3.3V and 5V)

Description
BD3813KS is a sound processor IC integrating gain
amplifier, volume, bass, and treble needed for applications
such as AV receiver, and mini component stereo into a
single chip. Adoption of BD3812F a 2-channel volume IC
enables a 6.1-channel and a 7.1-channel conversion.
BiCMOS process has resulted in a wide dynamic range
of 129dB.
