AD82584F-带I2S输出,用于智能音箱语音辨识的2x25W立体声数字音频功放



AD82584F-2x25W Stereo/1x50W Mono Digital Audio Amplifier With 30 bands EQ and DRC Functions

 

Description

AD82584F is a digital audio amplifier capable of driving 25W (BTL) each to a pair of 8 load speaker and 50W (PBTL) to a 4 load speaker operating at 24V supply without external heat-sink or fan requirement with play music. AD82584F provides advanced audio processing functions, such as volume control, 30 EQ bands, audio mixing, 3D surround sound and Dynamic Range Control (DRC). These are fully programmable via a simple I2C control interface. Robust protection circuits are provided to protect AD82584F from damage due to accidental erroneous operating condition. The full digital circuit design of AD82584F is more tolerant to noise and PVT (Process, Voltage, and Temperature) variation than the analog class-AB or class-D audio amplifier counterpart implemented by analog circuit design. AD82584F is pop free during instantaneous power on/off or mute/shut down switching because of its robust built-in anti-pop circuit.
