Part Number: ADC121S051

Hello,

does the ADC121S051 require a driver amplifier for the track-and-hold circuit, or is it internally buffered?

Regards
Tobi

  • Hello,

    The ADC121S051 does not have an internal buffer. An external driving amplifier would be needed.

    There is a great section on Precision labs, which is a selection of video tutorials on how to drive the input of a SAR ADC, called SAD ACD Input Drive Design
