efinition 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.
