GENERAL DESCRIPTION The AK4383 offers the perfect mix for cost and performance based audio systems. Using AKMs multi bit architecture for its modulator the AK4383 delivers a wide dynamic range while preserving linearity for improved THD+N performance. The AK4383 has full differential SCF outputs, removing the need for AC coupling capacitors and increasing performance for systems with excessive clock jitter. The AK4383 accepts 192kHz PCM data and 1-Bit DSD data, ideal for a wide range of applications including DVD-Audio and SACD. The AK4383 is offered in a space saving 20pin TSSOP package. FEATURES □ Sampling Rate Ranging from 8kHz to 192kHz □ 24-Bit 8 times FIR Digital Filter □ On chip SCF □ Digital de-emphasis for 32k, 44.1k and 48kHz sampling □ Soft mute □ Digital Attenuator (Linear 256 steps) □ PCM I/F format: 24-Bit MSB justified, 24/20/16-Bit LSB justified or I2S □ Master clock: 256fs, 384fs, 512fs or 768fs (PCM Normal Speed Mode) 128fs, 192fs, 256fs or 384fs (PCM Double Speed Mode) 128fs or 192fs (PCM Quad Speed Mode) 512fs or 768fs (DSD Mode) □ THD+N: -94dB □ Dynamic Range: 110dB □ DSD Data Input Mode □ High Tolerance to Clock Jitter □ Power supply: 4.75 to 5.25V □ Very Small Package: 20pin TSSOP (0.65mm pitch) □ AK4382 Pin Compatible
