AD82120
Overview
AD82120 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. AD82120 provides advanced audio processing functions, such as volume control, 32 EQ bands,.
