Hi all,

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…
