PCM1795DBR

ADCs/DACs - Special Purpose Overview

The PCM1795DBR is a stereo audio digital-to-analog converter manufactured by Texas Instruments. It features a 32-bit resolution and supports sampling rates up to 200 kHz. The device utilizes delta-sigma architecture with dual outputs and operates on a single power supply ranging from 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 123 dB and a total harmonic distortion plus noise of 0.0005%. It communicates via I2C or SPI interfaces and is housed in an SSOP-28 package suitable for surface mount applications.

ADCs/DACs - Special Purpose Feature Summary

• 32-bit resolution with 200 kHz maximum sampling rate
• High fidelity performance: 123 dB SNR and 0.0005% THD+N
• Flexible digital interface supporting I2C and SPI protocols
• Single-supply operation (4.75 V to 5.25 V) with bipolar outputs

ADCs/DACs - Special Purpose Applications

• Advanced segment audio systems
• Stereo DAC implementations requiring high dynamic range
• Professional audio equipment utilizing software control

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SSOP-28 footprint matches the target PCB layout design specifications exactly.

ADCs/DACs - Special Purpose Selection Notes

Select this component for designs requiring 32-bit processing capabilities within a 28-pin SSOP form factor. Compare against the PCM1795DB variant if tube packaging is preferred over reel options. Validate that the 4.75 V to 5.25 V supply range aligns with the system's power distribution network.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM1795 series of audio DACs from Texas Instruments. It serves as a successor to older architectures like the PCM1702, offering significantly higher resolution and lower distortion. The DBR suffix specifically denotes the tape-and-reel packaging format for automated assembly.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1795DB is a direct pin-compatible alternative differing only in packaging type (tube vs. reel). No other cross-model substitutes are confirmed in the provided data.
