The TLV320AIC10CPFBG4 device is an integrated high-performance audio analog-to-digital (ADC) and digital-to-analog (DAC) converter. It is primarily used in audio applications to take and convert a continuous analog audio stream into a digital format and vice versa. The device is supplied in a space-saving 4 mm × 4 mm LFCSP (Leadless Fine-pitch Chip Scale Package), which makes it ideal for space-constrained designs.

TLV320AIC10CPFBG4 Application Fields

The TLV320AIC10CPFBG4 device is ideally suited for mobile audio applications such as smart phone handsets and tablets, as well as other applications such as automotive panels and electronic gaming devices. The device can support a wide range of audio data formats, including I2S or PCM interfaces with sample rates supported up to 48kHz and resolutions up to 24-bits. It has a pair of assist pins (A1, A0) which can be used to select the audio data format quickly and without manual programming.

The device also has an integrated Direct Digital Synthesis (DDS) audio clock that can generate programmable audio clock frequencies between 8kHz and 48kHz for synchronization of input/output audio data. The DDS audio clock is adjustable using a simple resistor network. The DDS clock ensures that clocks are accurately reproducible from one device to the next, resulting in better audio performance and sound quality.

TLV320AIC10CPFBG4 Working Principle

The TLV320AIC10CPFBG4 device is a highly integrated audio CODEC that includes an ADC, a DAC, an audio clock generator, a programmable gain amplifier (PGA), and audio amplification blocks. The ADC of the device is used to convert an incoming audio signal into digital format, while the DAC is used to convert a digital signal into an analog audio signal. The audio clock generator block generates the necessary audio clock signals for ADC and DAC operations. The PGA block is used to adjust the gain level of the audio input signal for optimal conversion by the ADC. Lastly, the audio amplification block can be used to amplify the output signal from the DAC. The TLV320AIC10CPFBG4 device also includes a number of advanced features, such as an adjustable low-pass filter, a microphone bias generator, an adjustable high-pass filter, and a gain control block.

Conclusion

The TLV320AIC10CPFBG4 device is an ideal choice for mobile and other space-constrained audio applications. It offers high-quality audio performance and features such as an adjustable low-pass filter, adjustable high-pass filter, microphone bias generator, and adjustable gain control block. The device is also supplied in a small 4 mm × 4 mm LFCSP package, making it a desirable solution for compact designs.
