AK4712

Stereo Cap-less LINE-Amp and HD Video-Amp

GENERAL DESCRIPTION

The AK4712 is a High Definition A/V cap-less line driver. The AK4712 integrates the audio line driver,

SD/HD video filters and video drivers. Its A/V outputs are Ground-referenced and eliminate the need for

large A/V DC-blocking capacitors with a built-in Charge-pump circuit. The AK4712 achieves excellent A/V

performance by single 3.3V power supply. The AK4712 is ideal for a wide range of consumer HD

applications, such as portable A/V players, set-top boxes, and Blu-ray/DVD player systems. The AK4712

is offered in a space saving 28pin QFN package.
