The PCM1808-Q1 is high-performance, low-cost, single-chip, stereo analog-to-digital converter with single-ended analog voltage input. The PCM1808-Q1 uses a delta-sigma modulator with 64-times oversampling and includes a digital decimation filter and high-pass filter that removes the dc component of the input signal. For various applications, the PCM1808-Q1 supports master and slave mode and two data formats in serial audio interface.

The PCM1808-Q1 supports the power-down and reset function by means of halting the system clock.

The PCM1808-Q1 is suitable for wide variety of cost-sensitive consumer applications where good performance and operation with a 5-V analog supply and 3.3-V digital supply is required. The PCM1808-Q1 is fabricated using a highly advanced CMOS process and is available in a small, 14-pin TSSOP package.
