PCM2704DBRG4

PCM2704 is a DAC integrated circuit produced by Texas Instruments, and the PCM2704DBRG4 is the most popular IC in the PCM2704 series. It is used to convert digital audio data into audio voltage and is often used as digital-to-analog converter in digital audio players, home entertainment systems and multimedia PCs. This IC is capable of accepting a 16-signal bitstream from a digital audio source, and converting it into an audio output at 44.1 or 48KHz.

The PCM2704DBRG4 belongs to the Data Acquisition - ADCs/DACs - Special Purpose product category. It is a single-chip stereo digital-analog converter with 16-bit performance, providing a high-quality audio performance. The PCM2704DBRG4 goes beyond what traditional DACs are capable of, offering a range of unique features that make it well suited to many applications.

The working principle of the PCM2704DBRG4 is quite straightforward. It converts digital audio data into analog audio signals by taking the 16-bit digital audio data from a source, converting it into an analog voltage, and then outputting the analog voltage as current or voltage. This process is sometimes referred to as “quantizing,” as it involves taking digital signals with limited resolution, and converting them to analog signals with infinite resolution.

The PCM2704DBRG4 is suitable for a variety of applications, including digital audio players, MP3 players, home entertainment systems and multimedia PCs. In all of these applications, the PCM2704DBRG4 can be used to convert digital audio data into analog audio, allowing high-quality playback of digital sounds and music.

In addition to its use as a digital-to-analog converter, the PCM2704DBRG4 can also be used as an input device for recording audio. The IC includes a microphone preamplifier and anti-aliasing filters, allowing it to receive high-quality recordings with minimal noise.

The PCM2704DBRG4 is also used as an auxiliary component within audio systems, where it provides programmable gains and level shifting. By allowing precision adjustment of the audio output level, the PCM2704DBRG4 can be used to tailor the sound to the specific needs of the system.

Overall, the PCM2704DBRG4 is a versatile and reliable digital-to-analog converter, with a wide range of applications in digital audio players, home entertainment systems and multimedia PCs. It offers superior performance, reliability and functionality, making it an ideal choice for many digital audio projects.
