DESCRIPTION  
92-dBA Signal-to-Noise Ratio  
The TLV320AIC3104 is a low-power stereo audio  
codec with stereo headphone amplifier, as well as  
multiple inputs and outputs that are programmable in  
single-ended or fully differential configurations.  
Extensive register-based power control is included,  
enabling stereo 48-kHz DAC playback as low as 14  
mW from a 3.3-V analog supply, making it ideal for  
portable battery-powered audio and telephony  
applications.  
Supports Sample Rates From 8 kHz to 96  
kHz  
Digital Signal Processing and Noise  
Filtering Available During Record  
Six Audio Input Pins  
One Stereo Pair of Single-Ended Inputs  
One Stereo Pair of Fully Differential Inputs  
Six Audio Output Drivers  
The record path of the TLV320AIC3104 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.  
Stereo Fully Differential or Single-Ended  
Headphone Drivers  
Fully Differential Stereo Line Outputs  
Low Power: 14-mW Stereo 48-kHz Playback  
With 3.3-V Analog Supply  
Ultralow-Power Mode with Passive Analog  
Bypass  
Programmable Input/Output Analog Gains  
Automatic Gain Control (AGC) for Record  
Programmable Microphone Bias Level  
The TLV320AIC3104 contains four high-power output  
drivers as well as two fully differential output drivers.  
The high-power output drivers are capable of driving  
a variety of load configurations, including up to four  
channels of single-ended 16-headphones using  
ac-coupling capacitors, or stereo 16-headphones in  
a capless output configuration.  
Programmable PLL for Flexible Clock  
Generation  
I2C Control Bus  
Audio Serial Data Bus Supports I2S,  
Left/Right-Justified, DSP, and TDM Modes
