DESCRIPTION
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.
