AK4351 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.
