AK4556 3V 192kHz 24-Bit CODEC

The AK4556 is a low voltage 24bit 192kHz CODEC for high performance battery powered digital audio subsystems. The dynamic performance to power supply voltage ratio is very high, attaining 103dB and 106dB SNR for ADC and DAC, respectively. Sampling rates up to 216kHz are supported. The AK4556 reduces.
