9.3.3 ADC

The TLV320AIC3204 includes a stereo audio ADC, which uses a delta-sigma modulator with a programmable oversampling ratio, followed by a digital decimation filter. The ADC supports sampling rates from 8kHz to 192kHz. In order to provide optimal system power management, the stereo recording path can be powered up one channel at a time, to support the case where only mono record capability is required.

The ADC path of the TLV320AIC3204 features a large set of options for signal conditioning as well as signal routing:

  • Two ADCs
  • Six analog inputs which can be mixed and-or multiplexed in single-ended and-or differential configuration
  • Two programmable gain amplifiers (PGA) with a range of 0 to +47.5dB
  • Two mixer amplifiers for analog bypass
  • Two low power analog bypass channels
  • Fine gain adjustment of digital channels with 0.1dB step size
  • Digital volume control with a range of -12 to +20dB
  • Mute function
  • Automatic gain control (AGC)

In addition to the standard set of ADC features the TLV320AIC3204 also offers the following special functions:

  • Built in microphone bias
  • Stereo digital microphone interface
  • Channel-to-channel phase adjustment
  • Fast charge of ac-coupling capacitors
  • Anti thump
  • Adaptive filter mode
