AK4375A

Low-Power Advanced 32-bit DAC with HP/SRC

1. General Description

The AK4375A is a stereo advanced 32-bit high sound quality audio DAC with a built-in ground-referenced

headphone amplifier. An internal circuit is newly developed 32-bit digital filters for better sound quality,

achieving low distortion characteristics and wide dynamic range. The AK4375A also has a jitter cleaner with a

built-in SRC and a X’tal. The AK4375A is available in a 36-pin CSP package, utilizing less board space than

competitive offerings.
