[AK4373] 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.
