DSD1792ADBR

ADCs/DACs - Special Purpose Overview

The DSD1792ADBR is a stereo audio 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 and operates on a single 5V supply, with voltage specifications ranging from 4.75 V to 5.25 V. It provides two analog outputs and communicates via an SPI interface. Key performance metrics include a signal-to-noise ratio (SNR) of 127 dB and a total harmonic distortion plus noise (THD+N) of 0.001%. The component is housed in an SSOP-28 package and functions within a temperature range of -25°C to +85°C.

ADCs/DACs - Special Purpose Feature Summary

• 24-bit resolution with 192 kHz maximum sampling rate
• High fidelity performance: 127 dB SNR and 0.001% THD+N
• Single 5V power supply operation (4.75 V to 5.25 V)
• SPI serial interface for control and data input

ADCs/DACs - Special Purpose Applications

• High-fidelity stereo audio systems
• Professional audio equipment requiring low distortion
• Advanced segment DAC implementations

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'B' in the part number DSD1792ADBR against the official Texas Instruments datasheet to confirm packaging details, such as reel quantity or tape specifications. Ensure the design environment supports the required SPI interface and 5V logic levels. Confirm RoHS compliance status through the manufacturer's current documentation before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select the DSD1792ADBR when high dynamic range and low distortion are critical for stereo audio applications. Compare it with the PCM1792A series if I2C interface support is required instead of SPI. Verify that the SSOP-28 package footprint matches the PCB layout constraints and that the operating temperature range meets the system requirements.

ADCs/DACs - Special Purpose Part Context

The DSD1792ADBR belongs to the DSD1792A series of audio DACs from Texas Instruments. It shares architectural similarities with the PCM1792A series but differs in interface configuration, utilizing SPI rather than I2C/SPI dual-mode options found in some PCM variants. This series is designed for high-performance audio conversion using advanced segment technology.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1792ADBR is a related component in the same family offering similar electrical performance but includes I2C interface capability alongside SPI. Designers requiring I2C compatibility should consider this alternative while verifying pinout and software control register differences.
