AK4550 Overview
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.
