AK4377A
Low-Power Advanced 32-bit DAC with HP
1. General Description
The AK4377A is stereo advanced 32-bit high sound quality audio DAC with a built-in ground-referenced
headphone amplifier. An internal circuit integrates 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 AK4377A is available in a 36-pin CSP package, utilizing less board space than competitive offerings.
