AK4358
192kHz 24-Bit 8ch DAC with DSD Input
GENERAL DESCRIPTION
The AK4358 is eight channels 24bit DAC corresponding to digital audio system. Using AKM's advanced
multi bit architecture for its modulator the AK4358 delivers a wide dynamic range while preserving linearity
for improved THD+N performance. The AK4358 has full differential SCF outputs, removing the need for
AC coupling capacitors and increasing performance for systems with excessive clock jitter. The AK4358
accepts 192kHz PCM data and 1-Bit DSD data, ideal for a wide range of applications including
DVD-Audio and SACD.
