[AK4385] AK4385 108dB 192kHz 24-Bit 2ch ΔΣ DAC GENERAL DESCRIPTION The AK4385 offers the perfect mix for cost and performance based audio systems. Using AKM's multi bit architecture for its modulator the AK4385 delivers a wide dynamic range while preserving linearity for improved THD+N performance. The AK4385 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 AK4385 is offered in a space saving 16pin TSSOP package. FEATURES Sampling Rate Ranging from 8kHz to 192kHz 128 times Oversampling (Normal Speed Mode) 64 times Oversampling (Double Speed Mode) 32 ti [ ... ]
