Part Number: LF398-N Hello!
I wanted to check how the inputs of the LF398 are protected. From the datasheet, it appears the input voltage can be +/-18V before damage. Q1) this is irrespective of the power supply voltage, correct?
I see limited ESD protection…
Hello Fabian,
It would be really helpful if your could provide a schematic image of your LF398-N circuit showing the supply connections, input sources, output load, etc. Even though you have described your setup in detail it is always easier for us to…

Hello, I am working on a project with a boost converter where i need a sample and hold to keep the power value for a short period of time (10 - 50 ms). I have the circuit mounted on a PCB…
Part Number: LF398-N
Hello,
I am trying to use a LF398S8 sample and hold amplifier that I am giving an analog input Signal in the range of 0-10 V. However the output I receive always settles at about -14V no matter if I change the logic.
I am giving…
Part Number: LF398-N Hi,
I am using LF398N in my application. I am facing issues with the output voltage of the S/H which is not going more than 3.3v.
The input is varying from 0 to 5v.
VCC is 5v.
Logic is given to switching signal whose pulse width is…
Part Number: LF398-N Hi,
I'm using the LF398 sample and hold circuit for an acquisition chain and it's time for PCB layouting.
LF398 datasheet talks about guarding ring around input pin for the TO-99 package. Is it also doable with the SOIC package…
Part Number: LF398-N Other Parts Discussed in Thread: TINA-TI Hi all Would you mind if we ask LF398-N? We would like to simulate using TINA-TI. So, there is no LF398-N's TINA-TI model on the Web. Could you share us LF398-N's TINA-TI model? Kind regards…
Part Number: LF398-N Hello,
I would like to know if the LF398 will work if I connect it to a +/-12V Power Supply ?
Thank you in advance for your help
Kind regards,

Part Number: LF398-N Hello,
I supply the device with +15V at V+ and -15V at V-. When using the LF398N device (DIP package) an negative input of at least -10V is being hold at the output, whereas with the LF398M version (SOIC packages) the output is limited…
