Description

The AK4359 is eight channels 24bit DAC corresponding to digital audio system. Using AKM's advanced multi bit architecture for its modulator the AK4359 delivers a wide dynamic range while preserving linearity for improved THD+N performance. The product has single end SCF outputs, increasing performance for systems with excessive clock jitter. The AK4359 accepts 192kHz PCM data, ideal for a wide range of applications including DVD-Audio.
