A 5-V single-chip delta-sigma audio A/D converter with 111 dB dynamic range

A 5-V 24-b audio delta-sigma A/D converter has been developed. The single chip integrates stereo delta-sigma modulators, a voltage reference, and a decimation filter. A fourth-order cascaded delta-sigma modulator using a local feedback technique was employed to avoid overload without sacrifice in no...
