ADCs/DACs - Special Purpose - PCM1792DBG4 application field and working principle

The PCM1792DBG4 is an 8-channel digital-to-analog converter (DAC) manufactured by Texas Instruments. It is a high-resolution, low-noise, wide-dynamic range DAC that is available in two distinct versions, a dual 16-bit version and a single 12-bit enhanced version. It features a voltage mode current output, multiplexed data, low power consumption, firewire-like architecture, and a low-distortion output.

The PCM1792DBG4 DAC is designed for a wide range of audio applications, including digital-to-analog playback, home theater, automotive audio, and professional audio production. The device also has some specialized applications such as digital mixing consoles, broadcast mixing consoles, and high-end audio system controllers.

Features and Benefits

The PCM1792DBG4 features some unique features such as:

• High-performance, low-noise, wide-dynamic range.
• Wide range of audio applications and specialized uses.
• Low-power consumption with high accuracy.
• Firewire-like architecture to simplify designs.
• Low-distortion output and low jitter performance.
• Patented dithering technology.

Working Principle

The PCM1792DBG4 DAC is an analog-to-digital converter, meaning it converts digital input signals into analog output signals. At the core, a 8-bit digital-to-analog converter is used and a decoder is also utilized for multiplexing data to and from the DAC.

The digital input signals are converted to an analog current form, and then output from the DAC. The device is designed to support a wide dynamic range and the outputs can range from 0 volts to 5 volts in 8-bit increments. The PCM1792DBG4 also features dithering technology, which is used to reduce the effects of quantization noise and ensure superior audio quality.
