AK4309B
16Bit SCF DAC for Multimedia
General Description
The AK4309B is a 1bit stereo DAC for multimedia audio systems. A 1bit DAC can achieve monotonicity and
low distortion with no adjustment and is superior to traditional R-2R ladder based DACs. In the AK4309B, the
loss of accuracy from clock jitter is also improved by using SCF techniques for on-chip post filter. The
AK4309B includes continuous time filter with single end output and does not need any external parts. The
master clock can be either 256fs or 384fs, supporting various audio environment.
