AK4519, Low Power 20-bit ADC/DAC

AK4519 is low voltage 20bit A/D & D/A converter 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.

Analog signal input/output of the AK4519 are single-ended, therefore, external filter is not requ
