Asahi Kasei Microdevices AK4519

AK4519 is low voltage 20bit A/D & D/A converter for portable digital audio system. The AK4519 is low power dissipation and be able to powered-down ADC and DAC independently, so the AK4519 is suitable for portable digital audio system. In the AK4519, the loss of accuracy form clock jitter is also improved by using SCF techniques for on-chip post filter.
