AKD4381中文资料108dB 192kHz 24-Bit 2ch ΔΣ DAC数据手册AKM规格书

描述 Description

GENERALDESCRIPTION
The AK4381offers the perfect mix for cost and performance based audio systems. Using AKM's multi bit
architecture for its modulator the AK4381 delivers a wide dynamic range while preserving linearity for
improved THD+N performance. The AK4381 has  full differential  SCF outputs, removing the need for AC
coupling capacitors and 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 AK4381 is offered in a space saving 16pin TSSOP package.FEATURES
