1 Abstract

TLV320ADC5120/PCM5120-Q1 and TLV320ADC6120/PCM6120-Q1 devices are dual-channel, high-performance, audio analog-to-digital converters that have an extensive set of features that includes the following:

  • Programmable Gain Amplifier (PGA)
  • Digital volume control
  • A programmable microphone bias voltage
  • A phase-locked loop (PLL)
  • A programmable high pass filter (HPF)
  • Automatic Gain Control (AGC)
  • Dynamic Range Enhancer (DRE)
  • Dynamic Range Compressor (DRC)
  • Linear phase or low-latency filter modes for sample rates up-to 768 kHz

This application note describes how to configure the dynamic range enhancer (DRE) and dynamic range compressor (DRC) feature in TLV320ADC5120/PCM5120-Q1 and TLV320ADC6120/PCM6120-Q1 devices.
