DESCRIPTION  
The TLV320AIC3107 is a low power stereo audio  
codec with stereo headphone amplifier, and mono  
class-D speaker driver, as well as multiple inputs and  
outputs programmable in single-ended or fully  
differential configurations. Extensive register-based  
power control is included, enabling stereo 48-kHz  
DAC playback as low as 15 mW from a 3.3-V analog  
supply, making it ideal for portable battery-powered  
audio and telephony applications.  
Seven Audio Input Pins  
– Programmable as 6 Single-Ended or 3 Fully  
Differential Inputs  
– Capability for Floating Input Configurations  
Multiple Audio Output Drivers  
– Mono Fully Differential or Stereo  
Single-Ended Headphone Drivers  
– Single-Ended Stereo Line Outputs  
The record path of the TLV320AIC3107 contains  
integrated microphone bias, digitally controlled stereo  
microphone preamplifier, and automatic gain control  
(AGC), with mix/mux capability among the multiple  
analog inputs. Programmable filters are available  
during record which can remove audible noise that  
can occur during optical zooming in digital cameras.  
The playback path includes mix/mux capability from  
the stereo DAC and selected inputs, through  
programmable volume controls, to the various  
outputs.  
Mono 1W Class-D BTL 8Speaker Driver  
Low Power Consumption: 15-mW Stereo  
48-kHz Playback With 3.3-V Analog Supply  
Ultra-Low Power Mode with Passive Analog  
Bypass  
Programmable Input/Output Analog Gains  
Automatic Gain Control (AGC) for Record  
Programmable Microphone Bias Level  
Programmable PLL for Flexible Clock  
Generation  
I2C™ Control Bus  
Audio Serial Data Bus Supports I2S,  
The TLV320AIC3107 contains three high-power  
output drivers as well as two single-ended line output  
drivers, and a differential class-D output driver.  
Left/Right-Justified, DSP, and TDM Modes
