AD82178 Overview
AD82178 is a digital audio amplifier capable of driving 25W (31W peak) each to a pair of 8Ω load speaker (BTL) and 50W (62W peak) to a 4Ω load speaker (PBTL) operating at 24V supply without external heat-sink or fan requirement with play music. AD82178 provides advanced audio processing functions, such as volume control, 40 EQ bands, audio mixing, 3D surround sound and Dynamic Range Control (DRC) and Auto Gain...
