MP-A2D-PCM1822

MP-A2D-PCM1822 is a 6 to 24V DC, analog to digital converter board. The A2D-PCM1822 is a stereo audio ADC that efficiently converts both differential and single-ended signals into precise I2S signals. This ADC offers 24bit high resolution and supports sampling rates from 8kHz to 192kHz. With an impressive SNR of up to 119dB and ultra-low THD+N of 0.00047%, it ensures exceptional audio fidelity with minimal noise. The wide dynamic range of 111dB further enhances detailed audio playback quality. Featuring a 3-wire I2S output, the A2D-PCM1822 reduces radiation, facilitating easy compliance with EMI/EMC testing. It includes convenient switches for selecting modes, audio interfaces, input methods, and sampling rates, making it versatile for various audio projects. Its compact 3”x2” design, four mounting holes, and plug-and-play terminals ensure seamless integration into your audio systems.
