Features

The TLV320AIC1103PBSR CODEC has a number of features that make it well suited for portable audio applications. It supports single-ended I2S interface, a 32-bit/48 kHz ADC and DAC sample rate, has a high signal-to-noise ratio, supports two headphone output channels, and has a health monitoring capability.The CODEC supports standard audio connector formats, including TDM, I2S, and PCM, and is equipped with a 1dB volume step size and independent channel volume control for maximum flexibility. Additionally, the TLV320AIC1103PBSR CODEC offers headphone activity indicators, mute/input port control, and advanced power-saving features to minimize system power consumption.

Working Principle

The TLV320AIC1103PBSR CODEC is used to convert digital audio data into analog output signals that are suitable for driving headphones and other audio output devices. This conversion process is performed by the CODEC\'s ADC and DAC. The ADC is used to convert an analog input signal, such as speech or music, into a digital signal. The digital signal is then processed by the CODEC\'s digital filter to remove noise and other unneeded signals. The output of the digital filter is then converted back to analog by the DAC and sent out to the headphone or other output device. The TLV320AIC1103PBSR CODEC contains additional circuitry to improve the audio performance, such as a low-noise power supply, advanced power-saving features, and a health monitoring capability. Additionally, the CODEC supports two headphone output channels and offers a number of standard audio connector formats for maximum flexibility.

Conclusion

The TLV320AIC1103PBSR CODEC is a highly versatile, ultra-low power audio CODEC designed for portable audio applications. It offers excellent sound quality and signal-to-noise ratio, along with a wide range of features and functionality. Its single-ended system design, wide supply range, and advanced power saving features make it an ideal choice for battery-powered portable audio designs.
