PCM1793DBR

ADCs/DACs - Special Purpose Overview

The PCM1793DBR 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 a delta-sigma architecture with advanced sampling technology. Key electrical specifications include a signal-to-noise ratio (SNR) of 113 dB and a total harmonic distortion plus noise (THD+N) of 0.0004%. It operates on a single analog and digital power supply ranging from 4.5 V to 5.5 V. The component is housed in an SSOP-28 package and communicates via a serial 3-wire interface.

• Integrated internal voltage reference
• Serial 3-wire digital interface for control and data

ADCs/DACs - Special Purpose Applications

• High-fidelity audio systems
• Professional audio equipment
• Home theater receivers

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SSOP-28 package and reel packaging configuration as listed in official Texas Instruments documentation. Confirm RoHS compliance status through the manufacturer's current datasheet, as regulatory details may vary by production batch. Ensure the serial interface requirements match the system design before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select the PCM1793DBR when a 24-bit stereo DAC with 192 kHz support is required. Compare against the PCM1792A or PCM1796 if higher SNR (123-127 dB) or I2C/SPI interfaces are needed. This model offers a balance of high audio performance and a simple 3-wire serial interface within a standard SSOP-28 footprint.

ADCs/DACs - Special Purpose Part Context

This component belongs to the PCM179x series of high-performance audio DACs from Texas Instruments. It shares the SSOP-28 package form factor with related models like the PCM1792 and PCM1796 but differs in interface type and specific performance parameters such as SNR and gain error tolerance.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements within the same family include PCM1792DBR and PCM1796DBR. Note that these alternatives offer different SNR values (127 dB and 123 dB respectively) and may require I2C/SPI interfaces instead of the 3-wire serial interface used by the PCM1793.
