AK4359
192kHz 24-Bit 8ch DAC
GENERAL 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 AK4359 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.
