The AK4317 is a 1bit stereo DAC with channel separated volume and channel mixer. This DAC also includes 18bit digital filter and analog LPF. A 1bit DAC can achieve monotonicity and low distortion with no adjustment and is superior to traditional R-2R ladder based DACs. In the AK4317, the loss of accuracy from clock jitter is also improved by using SCF techniques for on-chip post filter. Therefore, the AK4317 is suitable for the system like STB including PLL circuit. Features
