PCM1803A - Texas Instruments

PCM1803A 96-kHz STEREO A/D CONVERTER

The PCM1803A device is high-performance, lowcost, single-chip stereo analog-to-digital converter with single-ended analog voltage input. The PCM1803A uses a delta-sigma modulator with 64and 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 P.
