AD85050 is a digital audio amplifier capable of driving. a pair of 8Ω,30W or a single 4Ω,60W speaker output. In headphone output mode, it can delivered 25mW into 32Ω load for head phone output. AD85050 provides advanced audio processing functions, such as volume control, 36 EQ bands, audio mixing, 3D surround sound and Dynamic Range Control (DRC). These are fully programmable via a simple I 2C control interface. Robust protection circuits are provided to protect AD85050 from damage due to accidental erroneous operating condition. The full digital circuit design of AD85050 is tolerant of noise and PVT (Process, Voltage, and Temperature) variation. AD85050 is pop free during instantaneous power on/off or mute/shut down switching because of its robust built-in anti-pop circuit
