GENERAL DESCRIPTION
The AK4397 is a high performance premium 32bit DAC for the 192kHz sampling mode of DVD-Audio
including a 32bit digital filter. Using AKM's multi bit architecture for its modulator the AK4397 delivers a
wide dynamic range while preserving linearity for improved THD+N performance. The AK4397 has full
differential SCF outputs, removing the need for AC coupling capacitors and increasing performance for
systems with excessive clock jitter. The AK4397 accepts 192kHz PCM data and 1-bit DSD data, ideal for
a wide range of applications including DVD-Audio and SACD. The AK4397 has a functional compatibility
with the AK4393/4/5 and lower power dissipation.
