JAJSLC0 March 2024 ADC3683-SP
PRODMIX
The ADC3683-SP is an unbuffered ADC, so a passive kick-back filter is recommended to absorb the glitch from the sampling operation. If the input is driven by a balun or a differential amplifier with low output impedance, a termination network may be needed. Additionally, a passive DC bias circuit is needed in AC-coupled applications which can be combined with the termination network.
