Description

The PCM1803A device is high-performance, low-cost, single-chip stereo analog-to-digital converter with single-ended analog voltage input. The PCM1803A uses a delta-sigma modulator with 64- and 128-times oversampling, and includes a digital decimation filter and high-pass filter, which removes the DC component of the input signal. For various applications, the PCM1803A supports master and slave modes and four data formats in serial interface. The PCM1803A is suitable for a wide variety of cost-sensitive consumer applications where good performance and operation from a 5-V analog supply and 3.3-V digital supply are required. The PCM1803A is fabricated using a highly-advanced CMOS process and is available in a small 20-pin SSOP package.
