the mix3008 is a high efficiency, high quality class-f audio amplifier with ultra low emi emitting which suitable for all portable products that has fm function. the mix3008’s internal built low pass filter removes all switching noise which traditional class-d amplifier generates; no switching noise means no fm interference. the high psrr and pop/click suppression performance make system design more flexibility. the low noise, filterless architecture eliminates the out filter, few external components saves the pcb space and the bom cost.

the mix3008 features shutdown and mute control and mode select functions. rf noise suppression techniques and differential design are used to suppress undesired noise.

the mix3008 is available in sop-16 pb-free package.
