The TLV320AIC3105 is a highly integrated low-power stereo audio codec with integrated stereo headphone/line amplifier, as well as multiple single-ended inputs and single-ended or fully differential programmable outputs. All the features of the TLV320AIC3105 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.
