The AK4665A includes a microphone/line input selector and an ALC circuit for input, and a stereo line output buffer, analog volume controls and capless stereo headphone amplifier for output. The AK4665A 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 31mW of power into 16Ω load. The AK4665A is housed in a 32pin QFN package, making it suitable for portable applications.
