BD3815KS

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.
