Data Acquisition

audio ADCautomotivePDM microphoneTDMI2CWQFN

PCM5120QRTERQ1 is a 20-pin automotive audio ADC for two analog channels or up to four PDM microphone channels, with configurable digital processing and serial audio output.

Best for

  • Automotive microphone and line-input acquisition
  • PDM microphone arrays requiring TDM output

Avoid if

  • A converter with more than two simultaneous analog input channels is required
  • The host cannot provide a supported audio clock interface

Check before use

  • Confirm analog versus PDM channel allocation
  • Validate serial-audio clock ratio and polarity
  • Follow VREF, AREG, and DREG decoupling requirements
