The PCM1808 device is a high-performance, low-cost, single-chip, stereo analog-to-digital converter with single-ended analog voltage input. The PCM1808 device 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 device supports master and slave mode and two data formats in serial audio interface.The PCM1808 device supports the power-down and reset functions by means of halting the system clock.The PCM1808 device is suitable for wide variety of cost-sensitive consumer applications requiring good performance and operation with a 5-V analog supply and 3.3-V digital supply. Fabrication of the PCM1808 device uses a highly advanced CMOS process.24-Bit Delta-Sigma Stereo A/D ConverterSingle-Ended Voltage Input: 3 Vp-pHigh Performance:THD+N: -93 dB (Typical)SNR: 99 dB (Typical)Dynamic Range: 99 dB (Typical)Oversampling Decimation Filter:Oversampling Frequency: x64Pass-Band Ripple: ±0.05 dBStop-Band Attenuation: -65 dBOn-Chip High-Pass Filter: 0.91 Hz (48 kHz)Flexible PCM Audio InterfaceMaster- or Slave-Mode SelectableData Formats: 24-Bit I2S, 24-Bit Left-JustifiedPower Down and Reset by Halting System ClockAnalog Antialias LPF IncludedSampling Rate: 8 kHz-96 kHzSystem Clock: 256 fS, 384 fS, 512 fSResolution: 24 BitsDual Power Supplies:5-V for Analog3.3-V for Digital(Different batches may result in different printing screens, which will not affect the use)Color: PurpleMaterial: PCBPackage Contents:3 x PCM1808 Module with pinOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
