Sound Processor

BD3452KS

No.10081EAT01

●Description

BD3452KS is a sound processor where the functions including Input Selector, 8ch Volume and Gain Amp required for

applications such as AV receivers, home theater systems and mini-component systems are integrated into a single chip.

Adopting the BiCMOS process achieves low distortion, low noise and a wide dynamic range.

●Features

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

2) Independent 8 channels for Master Volume (0 to -99 dB, MUTE 1dB/Step)

3) Supporting 2nd room entertainment

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

5) Built-in Output Gain Amp useful for adjusting output signal voltages (0 to 15dB, 1dB/Step)

6) BD3841FS (9-input selector), BD3843FS (6-input selector) and BUS are common to be controlled simultaneously.

7) Built-in 2ch output port

8) 2-wire serial control (For both 3.3V and 5V)

●Applications

AV receivers, home theater systems and mini-component systems

●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.

Over Ta25℃, reduce at the rate of 13mW/℃. When installed on the standard board (size: 70701.6mm).

●Operating conditions

It must function normally at Ta25℃.
