AK4373  
Low Power Stereo DAC with HP/SPK-Amp  
GENERAL DESCRIPTION  
The AK4373 is a low power stereo 24bit DAC with an integrated stereo headphone amplifier and a  
monaural speaker driver. It can be used for a variety of portable audio and media player applications,  
including game consoles, dedicated headphone drivers, personal navigation devices, and portable media  
players. The output drivers can be configured for three unique use cases: mono speaker driver or  
single-ended ac-coupled headphones which can be used as stereo line-out, DC-coupled BTL  
headphones and Pseudo Cap-less. The AK4373 operates off of a low-voltage power supply, ranging from  
2.2V to 3.6V. The output amplifiers operate at up to 4.0V of the headphone power supply. The device is  
packaged in a space-saving 32-pin QFN package.
