DESCRIPTION

The PCM1850/1851 is a high-performance, low-cost, single-chip stereo analog-to-digital converter with a single-ended

analog front end that consists of a 6-stereo-input multiplexer and wide-range PGA. The PCM1850/1851 includes a

delta-sigma modulator with 64-times oversampling, a digital decimation filter and a low-cut filter that removes the dc

component of the input signal. For various applications, the PCM1850/1851 supports two modes (master and slave) and

four data formats through a serial control interface, SPI for the PCM1850 and I²C for the PCM1851, respectively. The

PCM1850/1851 is suitable for a wide variety of cost-sensitive DVD/CD/MD recorder and receiver applications where good

performance and operation from a 5-V analog supply and 3.3-V digital supply is required. The PCM1850/1851 is fabricated

using a highly advanced CMOS process and is available in a small 32-pin TQFP package.
