Hi,

Anyone here can tell me how to connect a Sample and Hold IC LF398 in practical so that i can get a V(out) waveform as shown in the attached file? The V(in) and V(sample) is shown in the attached file also. Please provide me a simple schematic diagram if possible. The datasheet can be found in the following links:

http://pdf1.alldatasheet.com/datasheet-pdf/view/95569/ETC/LF398.html

 

If you want to sample when the digital input is low, and hold when it is high as shown in your waveforms, connect a voltage divider to pin 8 so that the voltage is 3.9V. The resistors can be on the order of tens of kohms. Apply the digital signal to pin 7.

 

Ron,

Can you draw a simple schematic diagram to me? Thanks alot!

 

I copied this from page 5 on the National datasheet, and made a few changes.

 

Thanks i can get the result already
