LM 358 - how to achieve a defined logic level at the output

[Leonel Aquino]

LM 358

I have a problem:
I have a pulsed signal between 0 and 12V with frequency between 2Hz and 3,5 KHZ in the input of a LM358, i need the following exit:
1.when the input is level " 1" or " 0" the output of LM 358 will be in 6V.

2. when the input pulse, the exit will have the same input pulse signal (0 - 12V).

Re: LM 358

I am really confused over this. Can you show a diagram of the input signal and output signal you want to see. It is not clear what difference there is between the kind of pulses you are trying to filter.

What is "1"? Logic one? But you have wrote

I have a problem:
I have a pulsed signal between 0 and 12V

So you have to explain what do you mean: TTL, CMOS logiv level or any others?

What is the purpose of your circuit? Please get in touch by email (PM = send a private message). I talk portuguese and may be I can help you.

Hi,

For your requirement why not use LM317?

Here you are going to control digitally. but you cannot get zero potantial directly.


Bye.

Hi

u can use an other OP or an LM393...because the LM358 is for some Applications not good for use...what ur supply Voltage? u have bipolar or single..
