GENERAL DESCRIPTIONThe AK4384 offers the perfect mix for cost and performance based audio systems. Using AKM's multi bitarchitecture for its modulator the AK4384 delivers a wide dynamic range while preserving linearity forimproved THD+N performance. The AK4384 integrates a combination of SCF and CTF filters increasingperformance for systems with excessive clock jitter. The 24 Bit word length and 192kHz sampling ratemake this part ideal for a wide range of applications including DVD-Audio. The AK4384 is offered in aspace saving 16pin TSSOP package.FEATURESo Sampling Rate Ranging from 8kHz to 192kHzo 128 times Oversampling (Normal Speed Mode)o 64 times Oversampling (Double Speed Mode)o 32 times Oversampling (Quad Speed Mode)o 24-Bit 8 times FIR Digital Filtero SCF with High Tolerance to Clock Jittero 2nd order Analog LPFo Single Ended Output Buffero Digital de-emphasis for 32k, 44.1k and 48kHz samplingo Soft muteo Digital Attenuator (Linear 256 steps)o I/F format: 24-Bit MSB justified, 24/20/16-Bit LSB justified or I2So Master clock: 256fs, 384fs, 512fs, 768fs or 1152fs (Normal Speed Mode)128fs, 192fs, 256fs or 384fs (Double Speed Mode)128fs, 192fs (Quad Speed Mode)o THD+N: -94dBo Dynamic Range: 106dBo Power supply: 4.5 to 5.5Vo Very Small Package: 16pin TSSOP (6.4mm x 5.0mm)LRCKBICKSDTIAudioDataInterfaceMCLKPDN∆ΣModulator AOUTL8XInterpolatorSCFLPFAOUTRVDDVSSVCOMDe-emphasisControlP/SμPInterfaceClockDividerSMUTE/CSNACKS/CCLKDIF0/CDTI∆ΣModulator8XInterpolatorDZFRDZFLSCFLPFATTATT106dB 192kHz 24-Bit 2ch ∆Σ DACAK4384AVR347 harman/kardon189
