TLV320AIC24CPFBR is a low-power, high-performance stereo audio codec. It enables the audio designer to develop products that require higher audio quality performance, while reducing power consumption. As a low-power audio codec, the AIC24 reduces current consumption by greater than 35% over existing CODECs. It features two integrated headphone amplifiers, two digital microphone inputs, Serial Audio Interface (SAI) ports, and line inputs and outputs.

The TLV320AIC24CPFBR is a comprehensive audio codec that combines two line-in and two line-out and two digital microphone inputs, with two headphone amplifiers. Each of the two SAI ports supports multiple protocols, and a software selectable function for mono microphone support. The device also offers advanced audio effects, such as EQ, AGC, and noise suppression. The device is designed for a variety of audio applications, including consumer audio, automotive infotainment, professional audio, and communication products.

Working principle:

The TLV320AIC24CPFBR acts as a bridge between the analog audio inputs and outputs and the digital audio processing. It performs sample rate conversion, time domain and frequency domain filtering, dynamic range compression, and noise reduction. The device has separate digital gain control for each input and output channel and specific filters and gain stages for different types of audio content, such as stereo, surround, and multi-channel sources. The digital audio modulation and coding algorithms accurately and effectively convert the digital information into high fidelity audio signals.

The device is equipped with two analog-to-digital (A/D) converters, two digital-to-analog (D/A) converters, and two headphone drivers. The digital audio signals from the A/D converters are transmitted to the audio processor, which processes them and generates the modified digital audio data. The digital audio data then passes through the D/A converters and the analog signals are sent to the outputs. The headphone drivers serve as the final stage in the signal processing path, amplifying the analog signal before it is output to the headphones.

The TLV320AIC24CPFBR features two integrated headphone amplifiers, two digital microphone inputs and two Serial Audio Interface (SAI) ports. The integrated headphone amplifiers provide up to 10 mW per channel into 16Ω loads, while the SAI ports support up to 8x oversampling. The integrated loudspeakers are dual-channel, allowing for stereo sound. The device also has a digital gain control for each input and output, and specific filters for different types of audio content. The device supports audio sample rates up to 48 kHz and accepts 16, 24, and 32 bit sample words.

In summary, the TLV320AIC24CPFBR is an interface-CODEC that can be used in a variety of audio applications. It offers efficient current consumption, two headphone amplifiers, two digital microphone inputs, two SAI ports, advanced audio effects, and digital gain control for each input and output. It also supports multiple audio sample rates and up to 8x oversampling. This device enables audio designers to develop products with higher audio quality performance while reducing power consumption.
