AK4396
Advanced Multi-Bit 192kHz 24-Bit ΔΣ 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.

Note 14. The passband and stopband frequencies scale with fs. For example, PB = 0.4535×fs (@±0.01dB), SB =
0.546×fs.
Note 15. The calculating delay time which occurred by digital filtering. This time is from setting the 16/20/24bit data of
both channels to input register to the output of analog signal.
