ASAHI KASEI [AK5351] AK5351 Enhanced Dual bit ∆Σ 20bit ADC GENERAL DESCRIPTION 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 suitable for digital surround and Hi-Fi audio application such as Car-audio, MD, etc. Analog inputs of the AK5351 are normally Full-differential inputs, while they are also acceptable Single-ended inputs. The AK5351 is available in a small 24pin VSOP package which will reduce your system space.
