The AK4388A offers the perfect mix for cost and performance based audio systems. Using AKM's multi bit architecture for its modulator, the AK4388A delivers a wide dynamic range while preserving linearity for improved THD+N performance. The AK4388A 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 AK4388A is offered in a space saving 16pin TSSOP package.
