ADD2010 is a 2Vrms output audio stereo DAC. Cap-less design can eliminate output dc-blocking capacitors for better low frequency response and save cost. ADD2010 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 ADD2010 from damage due to accidental erroneous operating condition. The full digital circuit design of ADD2010 is tolerant of noise and PVT (Process, Voltage, and Temperature) variation. ADD2010 is pop free during instantaneous power on/off or mute/shut down switching because of its robust built-in anti-pop circuit
