DSD1792DBR

ADCs/DACs - Special Purpose Overview

The DSD1792DBR is a stereo digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a 24-bit resolution and supports sampling rates up to 192 kHz. The device utilizes an advanced segment architecture for high-fidelity audio reproduction. Key electrical specifications include a signal-to-noise ratio (SNR) of 127 dB and a total harmonic distortion plus noise (THD+N) of 0.001%. It operates within a power supply voltage range of 4.75 V to 5.25 V and functions across a temperature range of -25°C to +85°C. The component is housed in a 28-pin SSOP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'BR' indicates reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets, as regulatory details may vary by production batch. Ensure the SSOP-28 footprint matches the target PCB design constraints.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high dynamic range and low noise floor in stereo audio paths. Compare against PCM1792 variants if I2C interface compatibility is required instead of SPI. Verify that the 5V analog and digital supply requirements align with the system power architecture.

ADCs/DACs - Special Purpose Part Context

The DSD1792DBR belongs to the DSD1792A series of audio DACs from Texas Instruments. It shares architectural similarities with the PCM1792 series but distinguishes itself through specific interface configurations and performance tuning optimized for advanced segment conversion techniques in high-performance audio circuits.

ADCs/DACs - Special Purpose Replacement Considerations

PCM1792DBR is a related variant within the same family. Verify interface compatibility, as some PCM1792 versions support I2C/SPI while others differ. Check pinout and electrical parameters to ensure direct interchangeability without circuit modification.
