PCM1801 描述
The PCM1801 is a low-cost, single-chip stereo analog-to-digitalconverter (ADC) with single-ended analog voltage inputs. The PCM1801 uses a delta-sigma modulator with 64 times oversampling, a digital decimation filter, and a serial interface that supports slave mode operation and two data formats. The PCM1801 is suitable for a wide variety of cost-sensitive consumer applications where good performance is required.
