AK5383
Enhanced Dual Bit Σ 96kHz 24-Bit ADC
GENERAL DESCRIPTION The AK5383 is a 24bit, 128x oversampling 2ch A/D Converter for professional digital audio systems. The modulator in the AK5383 uses the new developed Enhanced Dual Bit architecture. This new architecture achieves the wide dynamic range, while keeping much the same superior distortion characteristics as conventional Single Bit way. The AK5383 performs 110dB dynamic range, so the device is suitable for professional studio equipment such as digital mixer, digital VTR etc. FEATURES p Enhanced Dual Bit ADC p Sampling Rate: 1kHz~108kHz p Full Differential Inputs p S/(N+D): 103dB p DR: 110dB p S/N: 110dB p High Performance Linear Phase Digital Anti-Alias filter Passband: 0~21.768kHz(@fs=48kHz) Ripple: 0.001dB Stopband: 110dB p Digital HPF & Offset Calibration for Offset Cancel p Power Supply: 5V±5%(Analog), 3~5.25V(Digital) p Power Dissipation: 210mW p Package: 28pin SOP, VSOP p AK5393 Pin compatible
