PCM1680DBQ

ADCs/DACs - Special Purpose Overview

The PCM1680DBQ is a single-channel, 24-bit audio digital-to-analog converter (DAC) manufactured by Burr-Brown. It utilizes an enhanced multilevel delta-sigma architecture to support sampling rates up to 192 kHz. The device features a serial interface for data input and includes integrated digital filters. Designed for high-fidelity audio applications, it operates with low power consumption and provides high dynamic range performance suitable for professional audio equipment.

ADCs/DACs - Special Purpose Feature Summary

• 24-bit resolution with 192-kHz maximum sampling rate
• Enhanced multilevel delta-sigma modulation technology
• Integrated digital filter with selectable decimation ratios
• Serial audio interface compatible with standard PCM formats

ADCs/DACs - Special Purpose Applications

• High-end audio receivers and amplifiers
• Professional studio monitoring systems
• Home theater surround sound processors

ADCs/DACs - Special Purpose Part Context

The PCM1680 belongs to the Burr-Brown PCM16xx series of high-performance audio DACs. The DBQ suffix indicates a specific surface-mount package variant, typically a small-outline package, designed for automated PCB assembly. This component represents the transition from older multilevel architectures to more advanced sigma-delta designs in TI's audio portfolio.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements within the same family include the PCM1780 or PCM1681, though pinouts and channel counts may differ. Verify that any substitute supports the required 192-kHz sampling rate and maintains compatibility with the existing serial interface configuration.
