PCM3003 16/20-BIT SINGLE-ENDED ANALOG INPUT/OUTPUT STEREO AUDIO CODECS

The PCM3002 and PCM3003 are low-cost, single-chip stereo audio codecs (analog-to-digital and digital-to-analog converters) with single-ended analog voltage input and output. The ADCs and DACs employ delta-sigma modulation with 64-times oversampling. The ADCs include a digital decimation filter, and the DACs include an 8-times oversampling digital interpolati.
