AK5351 Enhanced Dual bit 20bit ADC

The AK5351 is a 20-bit, 64x oversampling rate(64fs), 2-channel A/D converter for stereo digital systems. The ∆Σ modulator in the AK5351 uses the new developed Enhanced Dual bit architecture. This new architecture achieves the wider dynamic range, while keeping much the same superior distortion characteristics as the conventional Single bit way. The AK5351 is.
