AK4384VT中文资料106dB 192kHz 24-Bit 2ch ΔΣ DAC数据手册AKM规格书

描述 Description

GENERAL DESCRIPTION
The AK4384 offers the perfect mix for cost and performance based audio systems. Using AKMs 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.FEATURES
