3X PCM1808 105dB SNR Audio Stereo ADC Single-Ended Analog-Input Decoder 24bit Amplifier Board Player Module

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.<br> The PCM1808 device supports the power-down and reset functions by means of halting the system clock.<br> 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.<br> 24-Bit Delta-Sigma Stereo A/D Converter<br> Single-Ended Voltage Input: 3 Vp-p<br> High Performance:<br> THD+N: -93 dB (Typical)<br> SNR: 99 dB (Typical)<br> Dynamic Range: 99 dB (Typical)<br> Oversampling Decimation Filter:<br> Oversampling Frequency: x64<br> Pass-Band Ripple: ±0.05 dB<br> Stop-Band Attenuation: -65 dB<br> On-Chip High-Pass Filter: 0.91 Hz (48 kHz)<br> Flexible PCM Audio Interface<br> Master- or Slave-Mode Selectable<br> Data Formats: 24-Bit I2S, 24-Bit Left-Justified<br> Power Down and Reset by Halting System Clock<br> Analog Antialias LPF Included<br> Sampling Rate: 8 kHz-96 kHz<br> System Clock: 256 fS, 384 fS, 512 fS<br> Resolution: 24 Bits<br> Dual Power Supplies:<br> 5-V for Analog<br> 3.3-V for Digital<br> (Different batches may result in different printing screens, which will not affect the use)<br> Color: Purple<br> Material: PCB<br> Package Contents:<br> 3 x PCM1808 Module with pin<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
