[AK4396]
AK4396
Advanced Multi-Bit 192kHz 24-Bit
∆Σ
DAC
GENERAL DESCRIPTION
The AK4396 is a high performance stereo DAC for the 192kHz sampling mode of DVD-Audio including a
24bit digital filter. Using AKM's multi bit architecture for its modulator the AK4396 delivers a wide dynamic
range while preserving linearity for improved THD+N performance. The AK4396 has full differential SCF
outputs, removing the need for AC coupling capacitors and increasing performance for systems with
excessive clock jitter. The AK4396 accepts 192kHz PCM data and 1-bit DSD data, ideal for a wide range
of applications including DVD-Audio and SACD. The AK4396 has a fully functional compatibility with the
AK4393/4/5 and lower power dissipation.
