Texas Instruments TLV320AIC3262 Ultra Low Power Stereo Audio Codec

Texas Instruments TLV320AIC3262 Ultra Low Power Stereo Audio Codec

Texas Instruments TLV320AIC3262 Ultra Low Power Stereo Audio Codec features digital microphone inputs and programmable outputs, PowerTune capabilities, enhanced fully-programmable miniDSP, predefined and parameterizable signal processing blocks, integrated PLL, and flexible audio interfaces. Extensive register-based control of power, input and output channel configuration, gains, effects, pin-multiplexing, and clocks are included, allowing this TI stereo audio codec to be precisely targeted to its application. TLV320AIC3262 audio codec features two fully-programmable miniDSP cores that support application-specific algorithms in the record and/or the playback path of the device. The miniDSP cores are fully software programmable. Targeted miniDSP algorithms, such as active noise cancellation, acoustic echo cancellation, or advanced DSP filtering, are loaded into the device after power-up. Combined with the advanced PowerTune technology, this TI device can execute operations from 8kHz mono voice playback to stereo 192kHz DAC playback, making it ideal for portable battery-powered audio and telephony applications.
