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℃)

*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 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℃.
