Overview
[AK4343] AK4343 Stereo DAC with HP/RCV/SPK-AMP GENERAL DESCRIPTION The AK4343 is a stereo DAC with a built-in Headphone-Amplifier, Rece iver-Amplifier and 1.
2W output Speaker-Amplifier.
The AK 4343 features analog mixing ci rcuits and PLL that allows easy interfacing in mobile phone and portable A/V player designs.
The AK4343 is availabl e in a 32pin QFN, utilizing less board space than competitive offerings.
