AK4558 108dB 216kHz 32-Bit CODEC

The AK4558 is a low voltage 32bit 216kHz CODEC for high performance battery powered digital audio subsystems. An internal circuit includes newly developed 32-bit Digital Filter achieving short group delay and high quality sound. In addition, “OSR-Doubler” technology is newly adopted, making the AK45.
