ADD2010-24 bits Audio Stereo DAC With DRC and EQ,2Vrms Line Out DataSheet

Description
    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 I2C 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.
