GENERAL DESCRIPTION
The AK4550 is a low voltage 16bit A/D & D/A converter for portable digital audio system. In the AK4550,
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 AK4550 are single-ended, therefore, any external filters are not required.
The AK4550 is suitable for portable digital audio system, as the AK4550 is lower power dissipation and a
smaller package than AK4518.
