The PCM1850A/1851A 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 PCM1850A/1851A 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 PCM1850A/1851A supports two modes (master and slave) and four data formats through a serial control interface, SPI for the PCM1850A and I2C for the PCM1851A. The PCM1850A/1851A 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 PCM1850A/1851A is fabricated using a highly advanced CMOS process and is available in a small 32–pin TQFP package.
