ASAHI KASEI

The AK4552 is a low voltage 24bit 96kHz A/D & D/A converter for digital audio system. In the AK4552,

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 AK4552 are single-ended, therefore, any external filters are not

required. As the package is 16pin TSSOP, the AK4552 is a suitable for minimizing system.
