BD3813KS-E2 ROHM

Sound Processors for Home Theater Systems 5.1ch Sound Processors No.10081EAT04 BD3813KS,BD3815KS Description The BD3813KS and BD3815KS sound processors integrate a gain amp and volume/bass/treble controls on a single chip, making them optimally suited for use in audio applications, such as AV receivers, home theater systems and mini-component systems. Used in combination with the BD3812F, a 2ch volume IC, the units enable 6.1ch and 7.1ch operation. In addition, utilization of a BiCMOS process ensures a wide dynamic range (129dB). Features 1) Wide dynamic range: 129dB (Tone Bypass, VOL=MUTE, IHF-A) 2) Independent 6 channels for Master Volume (0 to -95 dB, MUTE 1dB/Step) Implementation of a resistance ladder type circuit reduces residual noise and shock sounds during switching. 3) Low current consumption achieved through utilization of BiCMOS processes 4) Maximum output voltage: 4.2Vrms (Vcc=7V, VEE=-7V, RL=10k) 5) Built-in 5ch independent input gain amplifier - useful for amplifying input signals 6) Built-in 2ch output port 7) 2-wire serial control (for both 3.3V and 5V) Applications AV receivers, home theater systems and mini-component systems Line up matrix Parameter BD3813KS BD3815KS Mode Selector Yes Yes Input Gain 0 6 12dB 0 6 18dB Volume 0 to -95dB 1dB/Step 0 to -95dB 1dB/Step Bass, Treble 14dB 2dB/Step 14dB 2dB/Step Number of Ports 2 2 Package SQFP56 SQFP56 www.rohm.com 2010.06 - Rev.A 1/17 2010 ROHM Co., Ltd.
