ASAHI KASEI

The AK4569 is a 20bit CODEC with built-in Input PGA and Headphone Amplifier. The AK4569 includes a

microphone/line input selector and an ALC circuit for input, and a Mono line output buffer, analog volume

controls and stereo headphone amplifier for output. The AK4569 also features an analog mixing circuit

that allows easy interfacing in mobile phone and portable communication designs. The integrated

headphone amplifier features “pop-free” power-on/off, a mute control and delivers 8.7mW of power into

16Ω load via 6.8Ω series resistor. The AK4569 is housed in a 28pin QFN package, making it suitable for

portable applications.
