AK4519
Low Power 20 bit ∆Σ ADC&DAC with HPF
GENERAL DESCRIPTION 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 required.
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.
