AD82128B Overview
AD82128B is a digital audio amplifier capable of driving 32W (37W peak power) each to a pair of 8Ω load speaker (BTL) or 64W (74W peak power) to a 4Ω load speaker (PBTL) operating at 24V supply, that’s no external heat-sink or fan requirement during music playing. AD82128B provides advanced audio processing functions, such as volume control, 46 EQ bands, audio mixing, 3D surround sound and Dynamic Range Control...
