PCM1808 具有单端输入的 99dB SNR 立体声 ADC

PCM1808 描述

The PCM1808 is high-performance, low-cost, single-chip stereo analog-to-digital converter with single-ended analog voltage input. The PCM1808 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 supports master and slave mode and two data formats in serial audio interface.

The PCM1808 has many functions which are con- trolled through SPI serial-control port: power down, fade-in and fade-out, polarity control, etc.

The PCM1808 is suitable for wide variety of cost-sensitive consumer applications where good per- formance and operation with a 5-V analog supply and 3.
