PCM1681PWPR

ADCs/DACs - Special Purpose Overview

The PCM1681PWPR is an eight-channel audio digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a 24-bit resolution and supports sampling rates up to 200 kHz, including standard 192 kHz operation. The device utilizes delta-sigma architecture and offers a signal-to-noise ratio of 105 dB with a total harmonic distortion plus noise of 0.002%. It operates on a single power supply ranging from 4.5 V to 5.5 V and is housed in a 28-pin HTSSOP package. Control interfaces include I2C and SPI for configuration management.

ADCs/DACs - Special Purpose Feature Summary

• Eight independent DAC channels with 24-bit resolution
• Supports sampling frequencies up to 200 kHz
• High performance metrics: 105 dB SNR and 0.002% THD+N
• Integrated control via I2C and SPI serial interfaces

ADCs/DACs - Special Purpose Applications

• Multi-channel audio processing systems
• Professional audio equipment requiring high channel counts
• Digital audio playback devices with multiple output stages

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the tape-and-reel packaging format when sourcing. Confirm that the required operating voltage range of 4.5 V to 5.5 V aligns with the system power design. Ensure compatibility with the 28-HTSSOP footprint during PCB layout verification.

ADCs/DACs - Special Purpose Selection Notes

Select this component when eight simultaneous audio outputs are required within a single integrated circuit. The 24-bit resolution and low distortion specifications make it suitable for high-fidelity applications. Verify that the host controller supports the necessary I2C or SPI protocols for register configuration and data streaming.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM1681 series of audio DACs. The 'PWP' designation indicates the 28-lead HTSSOP package type, while the 'R' suffix specifies reel packaging. It is distinct from automotive-grade variants such as the PCM1681TPWPRQ1, which carries AEC-Q100 certification.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements within the same family include other PCM1681 variants with different packaging or temperature ratings. Cross-family substitution requires careful evaluation of interface compatibility and power supply requirements.
