DSD1793DB

ADCs/DACs - Special Purpose Overview

The DSD1793DB is a stereo audio digital-to-analog converter manufactured by Texas Instruments. It features a 24-bit resolution and supports sampling rates up to 192 kHz. The device utilizes a delta-sigma architecture with an advanced sampling stage for high-fidelity performance. Key electrical specifications include a signal-to-noise ratio of 113 dB and a total harmonic distortion plus noise of 0.0004%. It operates on a single 5 V power supply, with a voltage range of 4.5 V to 5.5 V. The component is housed in a 28-pin SSOP package and includes an internal voltage reference.

ADCs/DACs - Special Purpose Procurement Notes

Verify the manufacturer part number against official Texas Instruments documentation to ensure authenticity. Confirm that the SSOP-28 package matches the design requirements. Check for specific ordering suffixes if tape-and-reel packaging is required instead of tube. Ensure compliance with RoHS directives as indicated in the product specifications.

ADCs/DACs - Special Purpose Selection Notes

Select this component for designs requiring high dynamic range and low distortion in stereo audio applications. Verify that the system can accommodate the 4.5 V to 5.5 V operating voltage range. Ensure the PCB layout supports the SSOP-28 footprint and thermal requirements. Compare SNR and THD+N metrics against alternative DACs if stricter audio fidelity is needed.

ADCs/DACs - Special Purpose Part Context

The DSD1793DB belongs to the PCM1793 series of audio DACs from Texas Instruments. This series is designed for high-end audio equipment requiring precise digital-to-analog conversion. The device shares architectural similarities with other members of the family but is distinguished by its specific pinout and performance characteristics within the SSOP-28 package.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1793DB is a direct equivalent part number for the DSD1793DB. Verify pin compatibility and electrical parameters before substitution.
