The PCM 1808 is a high performance, low cost, monolithic stereo analog-to-digital converter with single-ended analog voltage input. The PCM 1808 unit uses a 64-fold oversampled Delta-Sigma modulator, including a digital decimation filter and a high-pass filter that removes the DC component of the input signal. For various applications, the PCM 1808 device supports both data formats in master-slave mode and serial audio interface.

The PCM 1808 device supports power down and reset functions by stopping the system clock.

The PCM 1808 device is suitable for a variety of cost-sensitive consumer applications that require good performance and operation with a 5V analog supply and a 3.3V digital supply. The PCM 1808 device is fabricated using a highly advanced CMOS process. The device is available in a small, 14-pin TSSOP package.
