About specification of LF398S

Hi all,
I would like to ask about LF398S.

LF398S:Precision Sample and Hold Amplifier in SO8 Package
www.analog.com/.../lf398s.html

① How is the timing of sample and hold determined?
(For example, How long does it take to hold the voltage from the sample start timing?)

② Does the sampling and hold timing change with the input waveform (e.g. triangle wave)?

Thanks

    Hi Takahiro,

    If we look at
    LF398N datasheet which is the LF398 DIP8 package, we can see the aperture time specification on page 4 (9-100).
    Aperture time is defined as the time when the signal is disconnected…
