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.
