AVR140
ASAHI KASEI
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.
