Overview
Proprietary dual-bit delta-sigma (∆Σ) architecture Sampling rate from 1kHz to 108kHz Full differential inputs Dynamic range = 117dB Signal-to-noise = 117dB Signal-to-(Noise + Distortion) = 105dB On-chip linear phase digital anti-alias filter - Passband from 0 to 21.768kHz at fs = 48kHz - Ripple = 0.001dB - Stopband attenuation = 110dB Selectable digital HPF or offset calibration Power supplies - Analog: 5V ± 5% - Digital: from 3V to 5.25V Low power dissipation: 470mW Small 28-pin SOP package Pin compatible with the AK5391, AK5392, and AK5383 The AK5393 is a 24-bit, 96kHz stereo Analog-toDigital Converter (ADC) that offers up to 117dB of dynamic range and a 105dB Signal-to-(Noise + Distortion) Ratio. The improved dynamic range and lowered distortion are achieved using an innovative dual-bit Σ∆ architecture that reduces power consumption and improves reliability.
