Sound Processor For Car Audio 56-Pin SQFP T/R

ROHM 5.1 sound processor ICs make it easy to configure 5.1 home theater systems. ·Wide dynamic range: 129dB (Tone Bypass, VOL=MUTE, IHF-A)
·Independent 6 channels for Master Volume (0 to -95 dB, MUTE 1dB/Step)
    Implementation of a resistance ladder type circuit reduces residual noise and a
    shock sound at switching.
·Low current consumption design achieved by adopting the Bi-CMOS process
·Maximum output voltage: 4.2Vrms (Vcc=7V, VEE=-7V, RL=10kO)
·Built-in 5ch independent input gain amplifier useful for amplifying input signals
·Built-in 2ch output port
·2-wire serial control (For both 3.3V and 5V)
