BD3452KS

Sound Processors for Home Theater System 7.1ch 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℃) Parameter Symbol Power Supply Voltage VCC VEE Input Signal Voltage VIN Ratings 7.5 *1 -7.5 VCC+0.3 to VEE-0.3 Unit V V Power Dissipation Pd 1300 *2 mW Operating Temperature Range Topr -20 to 75 ℃ Storage Temperature Range Tastg -55 to 125 ℃ *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.
