AK4355
192kHz 24-Bit 6ch DAC for DVD-Audio
GENERAL DESCRIPTION
The AK4355 offers the perfect mix for cost and performance based multi-channel audio systems. AKM's
advanced multi-bit architecture delivers a wide dynamic range and low outband noise. The AK4355 has
full differential SCF outputs, removing the need for AC coupling capacitors and increasing performance
for systems with excessive clock jitter. The 24 Bit word length and 192kHz sampling rate make this part
ideal for a wide range of application including DVD-Audio.
