Features:

・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=10kΩ)
・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)
