AK4384

106dB 192kHz 24-Bit 2ch DS DAC

GENERAL 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. The AK4384 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.
