AD82088D
Description
AD82088D is a digital audio amplifier capable of driving 25W (BTL) each to a pair of 8Ω load speaker and 50W (PBTL) to a 4Ω load speaker operating at 24V supply without external heat-sink or fan requirement with play music. AD82088D 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 Limiter (AGL).
