AK4359A
106dB 192kHz 24-Bit 8ch DAC
GENERAL DESCRIPTION
The AK4359A is an eight channels 24bit DAC corresponding to digital audio system. Using AKM's
advanced multi bit architecture for its modulator the AK4359A delivers a wide dynamic range while
preserving linearity for improved THD+N performance. The AK4359A has single end SCF outputs,
increasing performance for systems with excessive clock jitter. The AK4359A accepts 192kHz PCM data,
ideal for a wide range of applications including DVD-Audio.
