GENERAL DESCRIPTION
The AK4385 offers the perfect mix for cost and performance based audio systems. Using AKM's multi bit
architecture for its modulator the AK4385 delivers a wide dynamic range while preserving linearity for
improved THD+N performance. The AK4385 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
DVD-Audio. The AK4385 is offered in a space saving 16pin TSSOP package.
