AK4331ECB 32-Bit Stereo Digital-to-Analog Converter (DAC)

AKM’s AK4331ECB advanced, low-power DAC with built-in amp and SRC

Image of AKM's AK4331ECB 32-Bit Stereo Digital-to-Analog Converter (DAC)AKM’s AK4331ECB is a 2-channel, 32-bit, advanced, high sound quality, stereo digital-to-analog converter (DAC) including a built-in ground-referenced headphone amplifier. The DAC offers four types of 32-bit digital filters for better sound quality, attaining low distortion characteristics with a wide dynamic range. The IC also has a jitter cleaner with a built-in SRC and a crystal. The AK4331ECB is available in a 36-pin CSP package.
