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.
