GENERAL DESCRIPTION
The AK4387 offers the perfect mix for cost and performance based audio systems. Using AKM's multi bit
architecture for its modulator the AK4387 delivers a wide dynamic range while preserving linearity for
improved THD+N performance. The AK4387 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 AK4387 is offered in a
space saving 16pin TSSOP package.
