Texas Instruments  TLV320AIC3268IRGCR

The TLV320AIC3268 (AIC3268) provides users with an integrated method to implement an audio system with multiple digital and analog audio streams as sources, and multiple 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.

The AIC3268 supports a range of applications from mono 8kHz voice to stereo 192kHz music, making it ideal for wide variety of low power battery-operated and consumer audio applications.
