Description

The AK4384 offers the perfect mix for cost and performance based audio systems. Using AKM's multi bit architecture for its modulator the AK4384 delivers a wide dynamic range while preserving linearity for improved THD+N performance. It integrates a combination of SCF and CTF filters 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 AK4384 is offered in a space saving 16pin TSSOP package.
