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 f...
