BD3814FV

No.10081EAT05

●Description

BD3814FV is a 1-chip sound processor incorporating such functions as volume, bass, and treble, necessary for AV receivers,

home theater systems, and mini-audio systems. This IC adopts the Bi-CMOS process, and realizes low distortion, low noise,

and a wide dynamic range.

●Features

1) Dynamic range: 132dB (tone bypath, VOL = MUTE, IHF-A)

2) Master volume 6ch independent (0 to -95dB, MUTE 1dB/step)

3) Low current consumption design achieved by adopting the BiCMOS process

4) Maximum output voltage: 4.3Vrms (Vcc=7V, VEE=-7V, RL=10kΩ)

5) Built-in 2 OP amplifiers

6) 2-line serial control (for both 3.3V and 5V)

●Applications

AV receivers, home theater systems, mini-audio systems, TVs etc.

●Absolute maximum ratings (Ta=25℃)

*1 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 Reduced by 9 mW/C over 25C, when installed on the standard board (size: 70x70x1.6mm).

●Operating conditions

Must function normally at Ta=25℃.
