103dB SNR Stereo ADC with Single-Ended Inputs

The PCM1803 is high-performance, low-cost, single-chip stereo analog-to-digital converter with single-ended analog voltage input. The PCM1803 uses a delta-sigma modulator with 64-, 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 PCM1803 supports master and slave modes and four data formats in serial interface. The PCM1803 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 PCM1803 is fabricated using a highly advanced CMOS process and is available in a small 20-pin SSOP package.
