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 Converter Single-Ended Voltage Input: 3 Vp-p High Performance: THD+N: -93 dB (Typical) SNR: 99 dB (Typical) Dynamic Range: 99 dB (Typical) Oversampling Decimation Filter: Oversampling Frequency: x64 Pass-Band Ripple: ±0.05 dB Stop-Band Attenuation: -65 dB On-Chip High-Pass Filter: 0.91 Hz (48 kHz) Flexible PCM Audio Interface Master- or Slave-Mode Selectable Data Formats: 24-Bit I2S, 24-Bit Left-Justified Power Down and Reset by Halting System Clock Analog Antialias LPF Included Sampling Rate: 8 kHz-96 kHz System Clock: 256 fS, 384 fS, 512 fS Resolution: 24 Bits Dual Power Supplies: 5-V for Analog 3.3-V for Digital (Different batches may result in different printing screens, which will not affect the use) Color: Purple Material: PCB Package Contents: 2 x PCM1808 Module with pin Only the above package content, other products are not included.
