Functions and Features
• 4-channel bridge (BTL) power amplifier.
• IO max. 700 mA.
• With mute circuit
   (Affects all amplifier outputs, Amp 1 to Amp 8).
   (When the mute voltage is low, the outputs turn off;
   when the mute voltage is high, the outputs turn on).
• 5.0 V regulator built in (Uses external PNP transistor).
• Reset circuit built in (The reset output delay time can be
   adjusted through an external capacitor).
