1. General Description

The AK4376A 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 AK4376A is available in a 36-pin CSP package, utilizing less

board space than competitive offerings.
