2ch
Electronic Volume
BD3812F
●Description
BD3812F is an electronic volume having volume, gain amplifier functions necessary for applications in AV receivers, home
theatre systems, min-component systems and so forth. Having a chip select terminal, it can be controlled until 4 chips with
common bus line.
●Features
1) Residual noise : 1.2Vrms {dynamic range : 131dB (IHF-A)}
2) 2ch independent volume (0 to -103dB, MUTE 1dB/step)
3) 8ch at maximum available in combination of any of BD3811K1, BD3813KS, BD3814FV, BD3815KS (6ch volume)
in common bus line
4) It can be controlled until 4 chips with common bus line at the same time
5) Maximum output voltage : 4.2Vrms (Vcc=7, VEE=-7V, RL=10k
)
6) 2-line serial control (for both 3.3V and 5V)
7) Built-in Output gain amplifier for adjustment of output signal voltage (0, 6 to 18dB, 2dB/step)
8) Output mute controllable by serial data and external control terminal
●Applications
AV receivers, home theater systems, mini-component systems, etc.
●Absolute maximum ratings (Ta=25℃)

Even in the specified range of Power Supply Voltage, applying voltage only to the VCC side may
cause an excessive current to give a permanent damage to the IC.
When starting up power supplies, VEE and VCC should be powered on simultaneously or VEE first; then followed by VCC.
*2
Over Ta＝25°C, reduce at the rate of 4.5mW/°C. When installed on the standard board (size: 70x70x1.6mm).
●Operating conditions
It must function normally at Ta＝25°C.
