Harman Kardon AVR130 - DAC Description and Features; AK4358 24 bit DAC Description

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.
