10.1 Overview

The TLV320AIC3104 is a highly flexible, low-power, stereo audio codec with extensive feature integration, intended for applications in phones, headsets, portable gaming, communication, and entertainment applications. Available in a 5-mm × 5-mm, 32-lead QFN, the product integrates a host of features to reduce cost, board space, and power consumption in space-constrained, battery-powered, portable applications.

The TLV320AIC3104 consists of the following blocks:

  • Stereo audio multi-bit delta-sigma DAC (8 kHz–96 kHz)
  • Stereo audio multi-bit delta-sigma ADC (8 kHz–96 kHz)
  • Programmable digital audio effects processing (3-D, bass, treble, midrange, EQ, notch filter, de-emphasis)
  • Four audio inputs
  • Four high-power audio output drivers (headphone drive capability)
  • Two fully differential line output drivers
  • Fully programmable PLL
  • Headphone, headset jack detection available as register status bit
