Product Summary

The PCM1801U is a low-cost, single-chip stereo analog-to-digital converter (ADC) with single-ended analog voltage inputs. The PCM1801U 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 PCM1801U is suitable for a wide variety of cost-sensitive consumer applications where good performance is required.
