AK4555 - Low Power & Small Package 20-bit CODEC

The AK4555 is a low voltage 20bit A/D & D/A converter for portable digital audio system.

In the AK4555, 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 AK4555 are single-ended, therefore, any external filters
