6-channel volume IC for 6.1-channel
BD3813KS/BD3815KS
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. Dimension (Units : mm)

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)
