Sample and hold amplifer for ad convert?

Other Parts Discussed in Thread: TIDA-00003

Do you have any sample and hold amplifer can be used in 16bit or 18bit AD convert, the ADconvert's sample rate is about 10M?

Do you have any example design that I can used to sample the max value of a gassue pulse signal? The signal pulse's width is 1us.

  • Hi,
    Many ADCs have an internal sample-and-hold as the first stage, so you may not need an additional S/H in front of the ADC. We generally do not have dedicated S/H amplifiers as devices, but one can be created using a general purpose amplifier and a switched-capacitor network. Here is a link to a reference design:

    Many dedicated external S/H circuits are used at much higher switching speeds to interleave channels.
