GENERAL DESCRIPTION
The AK4383 offers the perfect mix for cost and performance based audio systems. Using AKMs multi bit architecture for its modulator the AK4383 delivers a wide dynamic range while preserving linearity for improved THD+N performance. The AK4383 has full differential SCF outputs, removing the need for AC coupling capacitors and increasing performance for systems with excessive clock jitter. The AK4383 accepts 192kHz PCM data and 1-Bit DSD data, ideal for a wide range of applications including DVD-Audio and SACD. The AK4383 is offered in a space saving 20pin TSSOP package.
