The AK4555 is a low voltage 20bit A/D & D/A converter for portable digital audio system.

In the AK4555, the loss of accuracy form clock jitter is also improved by using SCF techniques for on-chip post filter.

HPF for DC-offset cancel (fc=3.4Hz) Single-ended ADC - S/(N+D): 80dB@VDD=2.5V - Dynamic Range, S/N: 89dB@VDD=2.5V Single-ended DAC - Digital de-emphasis for 32kHz, 44.1kHz, 48kHz sampling - S/(N+D): 85dB@VDD=2.5V - Dynamic Range, S/N: 92dB@VDD=2.5V Audio I/F format: MSB First, 2’s Compliment - ADC, DAC: I2S Input/Output Voltage: 0.6 x VDD (=1.5Vpp@VDD=2.5V) High Jitter Tolerance Sampling Rate: 8kHz to 50kHz Master Clock: 256fs/384fs/512fs/768fs (fs=8kHz to 50kHz) 1024fs (fs=8kHz.
