Texas Instruments TLV320AIC3268 Ultra-Low Power Stereo Audio Codecs

Texas Instruments TLV320AIC3268 Ultra-Low
Power Stereo Audio Codecs

Texas Instruments TLV320AIC3268 Ultra-Low Power Stereo Audio Codecs integrate an audio system with multiple digital and analog audio streams as sources, and multple output devices such as high-powered audio amplifiers. The integrated miniDSP allows users to differentiate their products by enabling customization of signal processing on the audio streams. The low power consumption of this device is ideal for systems that are battery operated or that operate in a constrained power consumption environment. The AIC3268 is an integrated, low-power, low-voltage stereo audio codec and also features four digital microphone inputs, plus programmable outputs, predefined and parameterizable signal processing blocks and an integrated PLL. Extensive register-based control of power, input and output channel configuration, gains, effects, terminal-multiplexing and clocks are included, allowing the device to be precisely targeted to its application.
