AK4376
Low-Power Advanced 32-bit DAC with HP
1. General Description
The AK4376 is stereo advanced 32-bit high sound quality audio DAC with a built-in
ground-referenced headphone amplifier. An internal circuit newly developed 32-bit digital filters for
better sound quality, achieving low distortion characteristics and wide dynamic range. The sampling
frequency supports up to 384 kHz. The AK4376 is available in a 36-pin CSP package, utilizing less
board space than competitive offerings.
