  • PCM1822: Can I use something else than analog digital MEMS microphones?

    Part Number: PCM1822 Is this ADC specially designed for different MEMS microphone signals? Can I use near-field microphone signals in combination with a preamp to feed this ADC? If not, what are the risks?

  • PCM1822: Does AC-coupling the analog input pins violate the input voltage limitation of -0.3V?

    Resolved
    Part Number: PCM1822 The absolute maximum rating for the analog inputs to the ADC at the low end is -0.3V. Recommended anlog input range is 0 to AVDD (+3.3V). With a 2Vpp input, wouldn't AC-coupling cause the input signal to swing to -1V, violating the…
