Introduction

The TLV320DAC23IGQER is an application-specific digital-to-analog converter (DAC) designed for high-speed and digital audio transmission applications. It is the industry\'s first single-channel transmit FIFO audio CODEC compliant with the USB audio class 1.10 standard. The device provides users with a sampling rate of up to 24 bits and supports sample rates up to 48 kilohertz. It is also capable of providing flexible audio inputs and outputs with low THD+N and high dynamic range performance.

Applications

The TLV320DAC23IGQER can be used in a variety of applications such as music transmission over systems that require low latency, as well as professional audio.In music transmission applications, the TLV320DAC23IGQER can act as a self-contained audio interface for streaming audio over USB ports. It features a 24-bit data width, allowing for clear and accurate audio transmission without having to buffer multiple channels of data. Additionally, the AAC encoder included with the TLV320DAC23IGQER helps to further reduce latency, providing a less distorted sound output.The TLV320DAC23IGQER is also ideal for professional audio as it features advanced digital-to-analog and analog-to-digital conversion techniques, which help to produce clear and accurate audio. Additionally, its additional 24-bit support, with a maximum sampling rate of 48 kHz, allows it to capture a substantial audio frequency range.The audio CODEC is also ideal for use in applications that require the transmission of low-frequency audio signals, such as speech or sound effects, thanks to its low-noise performance.

Features

The TLV320DAC23IGQER features a wide range of features that make it an ideal choice for a variety of applications. Included among these features are:• 24-bit audio support at sampling rates up to 48 kHz• High dynamic range, low THD+N, and low-noise performance• Flexible audio input and output• Low-latency overall performance• Digital-to-analog and analog-to-digital conversion techniques• AAC encoder for further improved performance

Working Principle

The TLV320DAC23IGQER uses the Delta-Sigma Modulator (DSM) technique to provide digital-to-analog conversion. This technique uses an analog-to-digital converter (ADC) and a digital-to-analog converter (DAC) to convert the digital audio signal into an analog one.The DSM allows the user to increase the resolution of the signal without increasing the bit rate. The ADC is used to sample the incoming signal and convert it into a digital form. The DAC then uses this digital signal to reconstruct the analog equivalent.The DSM technique is preferred for its lower power consumption, higher SNR and flexibility. With this technique, the TLV320DAC23IGQER can provide users with high-quality audio transmission, low-latency performance, and flexible audio input and output performance.

Conclusion

The TLV320DAC23IGQER is a single-channel transmit FIFO audio CODEC that supports 24-bit audio at sampling rates up to 48 kHz and is compliant with the USB audio class 1.10 standard. This device can provide users with a wide range of audio I/Os, including analog-to-digital and digital-to-analog conversion, as well as low-noise performance. Using Delta-Sigma Modulator technique, the device can provide users with superior audio transmission quality, low latency performance, as well as flexible audio input and output performance. As such, this DAC device is an ideal choice for applications such as professional audio and music transmission systems.
