GENERAL DESCRIPTION 
The AK4358 is eight channels 24bit DAC corresponding to digital audio system. Using AKM's advanced 
multi bit architecture for its modulator the AK4358 delivers a wide dynamic range while preserving 
linearity for improved THD+N performance. The AK4358 has full differential SCF outputs, removing the 
need for AC coupling capacitors and increasing performance for systems with excessive clock jitter. The 
AK4358 accepts 192kHz PCM data and 1-Bit DSD data, ideal for a wide range of applications including 
DVD-Audio and SACD. 
FEATURES 
o Sampling Rate Ranging from 8kHz to 192kHz 
o 24Bit 8 times Digital Filter with Slow roll-off option 
o THD+N:     -94dB 
o DR, S/N:   114dB
 
o High Tolerance to Clock Jitter 
o Low Distortion Differential Output 
o DSD Data input available 
o Channel Independent Digital De-emphasis for 32, 44.1 & 48kHz sampling 
o Zero Detect function 
o Channel Independent Digital Attenuator with soft-transition (3 Speed mode) 
o Soft Mute 
o 3-wire Serial and I
2
C Bus µP I/F for mode setting 
o I/F format: MSB justified, LSB justified (16bit, 20bit, 24bit), I
2
S, TDM or DSD 
o 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)
 
o
 Power Supply:  4.75 to 5.25V 
o 48pin LQFP Package
