AK4397
Premium 32-Bit DAC with PCM/DSD input
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, which remove the need for AC coupling capacitors and increase 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.
