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 chara.
