11 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
11.1 Application Information
The TLV320AIC3107 is a highly integrated low-power stereo audio codec with integrated stereo headphone/line,
and mono class D amplifier, as well as multiple inputs and outputs that are programmable in single-ended or fully
differential configurations. All the features of the TLV320AIC3107 are accessed by programmable registers.
External processor with I2C protocol is required to control the device. It is good practice to perform a hardware
reset after initial power up to ensure that all registers are in their default states. 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.
