Features

1) 2-channel volume and sound quality control. 2) Absorption of volume deviation between input sources and improved S / N ratio, for better sound quality, using an AGC circuit. 3) Control through I2C BUS serial control. 4) Internal pseudo-stereo circuit provides phase-shift matrix surround effect. !Absolute maximum ratings (Ta = 25°C) Parameter Power supply voltage Power dissipation Operating temperature Storage temperature Symbol VCC Pd Topr Tstg Limits 10.0 1250∗ −25~+75 −55~+125 Unit V mW °C °C ∗Reduced by 12.5mW for each increase in Ta of 1˚C over 25˚C. !Recommended operating condition.
