AK4319A
18Bit SCF DAC
General Description
The AK4319A is a high performance 1bit stereo DAC for digital audio systems. A 1bit DAC can achieve
monotonicity and low distortion with no adjustment. On chip SCF filter makes the device less affected to the
clock jitter and also suppresses the undesirable radio emission noise. The device equips differentially
configurated output pins, but either of the pins can be used as single-end. The AK4319A achieves lower Out-
band noise characteristic and it is suitable for digital broadcasting tuner and other digital audio applications.
