AD82120B Overview
AD82120B is a digital audio amplifier capable of driving 25W each to a pair of 8Ω load speaker (BTL) or 50W to a 4Ω load speaker (PBTL) operating at 24V supply, that’s no external heat-sink or fan requirement during music playing. AD82120B provides advanced audio processing functions, such as volume control, 46 EQ bands, audio mixing, 3D surround sound and Dynamic Range Control (DRC). These are fully programmable...
