the mix3004 is is a high efficiency, 3w/channel stereo class-d audio power amplifier with earphone amplifier. 64-step dc volume control minimizes external components and allows speaker volume control and earphone volume control. it offers low thd+n, to produce high-quality sound reproduction. a low noise,filterless architecture eliminates the out filter, it required few external components for operation to
save the board space and cost.
the mix3004 features shutdown and mute controls functions. high psrr and differential architecture provide increased immunity to noise and rf rectification.
the mix3004 is available in a ssop-24 and ssop-24 pb-free package.
