GENERAL DESCRIPTION
The AK4342 is a 24-bit stereo DAC with 2Vrms lineout, an integrated headphone amplifier, and an
auxiliary line output. The AK4342 features an analog mixing circuit that enables a simple interface to external analog audio sources. The integrated headphone amplifier features “click-free” power-on/off, a mute control and delivers 62.5mW of power at 16?@ 3.3V. The AK4342 is controlled via an I2C or 3-wire interface, and is available in a 32-pin QFN package.
