AK4383 Datasheet | Asahi Kasei Microdevices

DESCRIPTION The AK4383 offers the perfect mix for cost and performance based audio systems. Using AKM's 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 192k Hz PCM data and 1-Bit DSD data, ideal for a wide range of applications including DVDAudio and SACD. The AK4383 is offered in a space saving 20pin TSSOP package.
