AK4365 Datasheet | Asahi Kasei Microdevices

DESCRIPTION The AK4365 is 20bit DAC with built-in PLL and Headphone Amplifier. The PLL input crystal frequency is matched to typical mobile phone clock frequencies. The AK4365 features an analog mixing circuit that allows easy interfacing in mobile phone and portable munication designs. The integrated headphone amplifier features “click-free” power-on/off, a mute control and delivers 10m W of power at 16Ω. The AK4365 is housed in a 28pin QFN package, making it suitable for portable applications.
