Product Summary

The AK4397EQ 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 AK4397EQ delivers a wide dynamic range while preserving linearity for improved THD+N performance. The AK4397EQ has full differential SCF outputs, removing the need for AC coupling capacitors and increasing performance for systems with excessive clock jitter.
