+
+description: |
+ The TLV320ADCX140 are multichannel (4-ch analog recording or 8-ch digital
+ PDM microphones recording), high-performance audio, analog-to-digital
+ converter (ADC) with analog inputs supporting up to 2V RMS. The TLV320ADCX140
+ family supports line and microphone Inputs, and offers a programmable
+ microphone bias or supply voltage generation.
