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.
