16/20/24/32-Bit Data  
DESCRIPTION  
Supports Rates From 8 kHz to 96 kHz  
3D/Bass/Treble/EQ/De-Emphasis Effects  
The TLV320AIC3105 is a low-power stereo audio  
codec with multiple single-ended inputs and and a  
stereo headphone amplifier. The output stages 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.  
Flexible Power Saving Modes and  
Performance are Available

92-dBA Signal-to-Noise Ratio  
Supports Rates From 8 kHz to 96 kHz  
Digital Signal Processing and Noise  
Filtering Available During Record  
The record path of the TLV320AIC3105 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.

Low Power: 14-mW Stereo 48-kHz Playback  
With 3.3-V Analog Supply  
Ultralow-Power Mode with Passive Analog  
Bypass  
The TLV320AIC3105 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-Ω headphones using  
ac-coupling capacitors, or stereo 16-Ω headphones in  
a capacitorless output configuration.

I2C Control Bus  
Audio Serial Data Bus Supports I2S,  
The stereo audio DAC supports sampling rates from  
8 kHz to 96 kHz and includes programmable digital  
filtering in the DAC path for 3D, bass, treble,  
midrange effects, speaker equalization, and  
de-emphasis for 32-kHz, 44.1-kHz, and 48-kHz rates.  
The stereo audio ADC supports sampling rates from  
8 kHz to 96 kHz and is preceded by programmable  
gain amplifiers or AGC that can provide up to 59.5-dB  
analog gain for low-level microphone inputs. The  
TLV320AIC3105 provides an extremely high range of  
programmability for both attack (8–1,408 ms) and for  
decay (0.05–22.4 seconds). This extended AGC  
range allows the AGC to be tuned for many types of  
applications.
