The PCM1792DBR integrates the PCM1792A Delta-Sigma DAC, providing advanced features and an exceptional audio performance with up to 21 bit audio resolution and up to 192kHz sampling rates. The DAC offers excellent dynamic performance, high output drive capability and features low jitter performance.

The PCM1792DBR is a high-quality full duplex stereo DAC with complete digital interface compatible with popular audio formats. It can be used in multiple-channel applications; up to eight channels can be supported. It offers extended dynamic range, high output swing, minimal distortion and a wide supply voltage of 4.5V to 6V. It also provides extensive control and programmability via an intuitive control and data interface.

The versatile and feature-rich PCM1792DBR is ideal for applications in the broadcast, home theater and professional audio markets. It is well-suited for applications such as stereo audio playback, multi-channel audio playback, studio recording and mastering, real-time audio processing, surround sound production, and gaming audio. It is an ideal solution for power-sensitive and space-constrained audio applications.

The PCM1792DBR is built using a unique differential sigma-delta modulator architecture. The core of the architecture is two stages of delta-sigma modulator, each consisting of a multi-bit DAC, power supply, and clock source. The first stage of the modulator contains only a DAC, and its output is used to drive the second stage, which consists of a second DAC, power supply, and clock. The first stage is used to convert the digital input signal into a differential voltage, which is then used to drive the second stage. The second stage is used to convert the differential voltage into an analog output signal.

The output of the PCM1792DBR is a 16-bit wide analog signal with a sampling rate of up to 192 kHz. Additionally, the DAC supports 4, 8 and 16 times over-sampling and a variety of different control data formats. The DAC supports various control signals such as volume control, mute, and channel selection. These control signals are used to customize the output of the DAC.

The PCM1792DBR is a high-performance DAC that offers a variety of features and benefits. It features low phase noise, low output jitter, and high linearity. It also supports up to 192kHz sampling rates and up to16 times oversampling. It offers a wide supply voltage range of 4.5V to 6V and wide operating temperature range of -40°C to 85°C. The DAC also supports a wide range of audio formats, including AIFF, WAV, PCM, ABR, and MP3.

In conclusion, the PCM1792DBR is a high-performance and feature-rich multicomponent digital-to-analog converter ideal for applications in the broadcast, home theater, and professional audio markets. It features low phase noise, low output jitter, and high linearity. It supports up to192 kHz sampling rates and up to 16 times oversampling. Additionally, it offer a wide supply voltage range and a wide operating temperature range. It is an ideal solution for power-sensitive and space-constrained audio applications.
