PCM1800 Overview
Description
The PCM1800 is a low-cost, single-chip stereo analog-to-digital converter (ADC) with single-ended analog voltage inputs. The PCM1800 uses a delta-sigma modulator with 64 times oversampling, including a digital decimation filter and a serial interface which supports both master and slave modes and four data formats.
