Cxau4129 is a monophonic digital audio power amplifier (D+ class)Because of the unique closed-loop gain feedback compensation technology its audio index reaches the standard of class AB

It uses bridge mode, which can promote 4 or 8 ohm loudspeaker. The efficiency of the amplifier is close to 90%, small size, no heat sink, and has built-in input coupling capacitor, There are no peripheral components. In addition, it has the function of mute control (logic level control). After mute, the static current is less than 1mA. It is suitable for LCD-TV, walkie talkie, USB speaker and portable DVD
