Description

The AK4380 offers the perfect mix for cost and performance based audio systems. Using AKM's multi bit architecture for its modulator the AK4380 delivers a wide dynamic range while preserving linearity for improved THD+N performance. The product integrates a combination of SCF and CTF filters, removing the need for high cost external filters and increasing performance for systems with excessive clock jitter. The 24 Bit word length and 96kHz sampling rate make this part ideal for a wide range of applications including DVD and AC-3 systems. The AK4380 is offered in a space saving 16pin TSSOP package.
