AK4351  
18Bit Advanced Multi Bit DS 2ch DAC  
GENERAL DESCRIPTION  
The AK4351 is a high cost performance 18bit stereo DAC for low-end digital audio systems. The  
modulator in the AK4351 uses the new developed Advanced Multi Bit architecture with wide dynamic  
range. The analog outputs are filtered in the analog domain by a combination of SCF and CTF.  
Therefore, any external filters are not required. The SCF techniques also improve the loss of accuracy  
from clock jitter. Therefore, the AK4351 is suitable for the system like STB including PLL circuit. The  
AK4351 is available in very small 16pin TSSOP package, which reduces system space.  
FEATURES  
· Sampling Rate Ranging from 8kHz to 50kHz  
· 128 times Oversampling  
· Perfect filtering  
18bit 8 times FIR Interpolator with 57dB attenuation  
2nd order LPF  
Total Response: ± 0.2dB at 20kHz  
· On chip Buffer with Single End Output  
· Digital de-emphasis for 44.1kHz sampling  
· I/F format: MSB justified, 16/18bit LSB justified or I2S  
· Master clock: 256fs or 384fs  
· TTL Level Digital Interface  
· THD+N: -88dB  
· D-Range: 96dB  
· High Tolerance to Clock Jitter  
· Power supply: 4.5 to 5.5V  
· Very Small Package: 16pin TSSOP (6.4mm x 5.0mm)
