GENERAL DESCRIPTION

The AK4382 offers the perfect mix for cost and performance based audio systems. Using AKMs multi bit architecture for its modulator the AK4382 delivers a wide dynamic range while preserving linearity for improved THD+N performance. The AK4382 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 applications including DVDAudio. The AK4382 is offered in a space saving 16pin TSSOP package.
