Low-Power Advanced 32-bit Mono DAC with HP
1. General Description
The AK4332 is an advanced 32-bit high sound quality mono audio DAC with a built-in ground-referenced
headphone amplifier. It has four types of 32-bit digital filters for better sound quality, achieving low
distortion characteristics and wide dynamic range. The AK4332 accepts PCM Data, PDM Data and DSD
Data. It is available in a 30-pin CSP package, utilizing less board space than competitive offerings.
