How to Choose
When selecting a Burr Brown DAC, consider the application’s specific needs. Key factors include supported sampling rates (192 kHz is common for high-end audio), bit depth (24-bit or higher for fidelity), and output type (single-ended vs. differential). Pay attention to the total harmonic distortion (THD), signal-to-noise ratio (SNR), and whether the DAC supports features like digital filtering, low jitter clocking, or integrated volume control. Compatibility with your existing digital interface (I2S, SPDIF, etc.) is also crucial. Finally, assess your budget and whether you need a chip for DIY projects or a ready-made module for professional use.
