Spurious-Free Dynamic Range

Term Definition
Spurious-Free Dynamic Range

SFDR is an important measure which characterizes the dynamic performance of ADCs and DACs. It specifies the ratio between the amplitude of the fundamental and the strongest spurious signal. SFDR together with ENOB give a good understanding of the dynamic performance of SP Devices high-performance digitizers.


  • "The technical and intellectual support from the team at Teledyne SP Devices has been playing an important role in our research."

    Associate Professor at Hong Kong University (HKU)
    who has implemented a system supporting line scan rates of 10M lines/s


  • "I can state that ADQ7DC is the best digitizer for high resolution positron lifetime spectroscopy I found on the market."

    prof. Jakub Čížek, Department of Low Temperature Physics at Charles University, Prague


  • "The ADQ7DC digitizer is the best device of this type available on the market with high sampling rate, wide analog bandwidth, quality and stability of signal acquisition. A professional team of the SP Devices engineers ensure support and quick response to the inquiries."
