GENERAL DESCRIPTION
The AK4534 targeted at PDA and other low-power, small size applications. It features a 16-bit stereo
CODEC with a built-in Microphone-Amplifier, Headphone-Amplifier and Speaker-Amplifier. Input circuits
include a Microphone-Amplifier and an ALC (Auto Level Control) circuit. The AK4534 is available in a
52-QFN, utilizing less board space than competitive offerings.
