The TLV320AIC10IPFBG4 is a multi-channel, low-power audio codec designed for analog to digital/digital to analog conversion in consumer, automotive, and professional audio applications. Its powerful audio signal processing capability, high performance analog and digital interfaces, and programmable components make it an ideal choice for application-specific processing solutions. The device consists of three parts: a CODEC, a control interface with I2C, and a programmable gain amplifier (PGA).

Application Fields

The TLV320AIC10IPFBG4 is applicable for a wide range of consumer, automotive, and professional audio applications. It can be used for Bluetooth and USB audio, flat panel PCs, digital media players, automotive audio systems, and portable audio devices, among others. It is also a suitable choice for home entertainment audio applications and media devices.

The device enables robust system performance through a variety of audio signal processing blocks, including sample rate converters, A-law/mu-law compander, automatic gain control, peak limiters and mixers. Its powerful programmable mixer supports up to 8 inputs and 8 outputs, allowing for flexible routing of audio signals to meet various application needs.

The device also features integrated I2C control interface with built-in support for I2C Master and Slave mode operation, allowing for integration with external control systems. The control interface can be used to adjust device parameters, such as gain, roll-off filter, input mute, and output mix. The integrated PGA provides up to 1 dB step control resolution, allowing the user to set precise gain levels.

Working Principle

The TLV320AIC10IPFBG4 utilizes a codec approach for audio signal conversion. In codec-based systems, an analog input signal is first converted to a digital signal by an ADC, and then processed by the codec\'s digital signal processing blocks. The processed signal is then converted back to an analog signal by a digital to analog converter (DAC). This is a less-expensive alternative to a single-chip DAC and/or ADC solution, and also offers higher performance, as the device can be optimized for specific customer or application requirements.

The device contains an on-board preamplifier, which supports up to +15 dB of microphone boost. The device also offers an on- board AGC loop, which enables automatic gain control and peak limiting to maintain the desired level of audio quality. The device comes with a wide range of filters and effects, such as equalizers, noise reduction, and delay and reverb, allowing for audio processing tailored to the specific application and customer requirements.

The device also supports a variety of digital audio interfaces, including I2S, PCM, AC3, and S/PDIF, allowing it to be integrated with a variety of audio applications. Its integrated I2C bus provides control over a variety of features, such as phase and gain control, input and output selection and mute, and digital audio format. The programmable mixer provides the flexibility to route and mix up to eight audio channels, allowing for flexible applications.

The device also features a low- power operation mode that allows for a longer battery life in mobile applications. Additionally, its programmable sample rate converter supports sample rates up to 96 kHz, allowing it to be used in HD audio applications. The device also supports a variety of popular audio formats, such as Dolby Digital and AAC, enabling it to be used in a wide range of audio applications.

Conclusion

The TLV320AIC10IPFBG4 is a powerful, low-power CODEC designed for a variety of consumer, automotive, and professional audio applications. Its powerful audio signal processing blocks, high performance analog and digital interfaces, and programmable components make it an ideal choice for application-specific processing solutions. With its integrated I2C interface, programmable mixer, and low-power operation, this device is well suited for a wide range of audio applications.
