I know I may have to implement some hysteresis into this circuit. Its purpose is to protect Q1 from too much base current, which is datqsheet a problem in this circuit. Mar 14, 20, 5, Dec 28, Yes, my password is: Dec 28, 5. Why does your schematic drawing software produce backwards negative white lines on a black background instead of a normal positive image?? Hopefully, I was clear in my explanation.
You only need 4mA, so beta isn’t a critical parameter. That will also help with the max output voltage. I am trying to setup a constant current source using a 2n and a Motorolla LMN.
It should not be used a design parameter for several reasons. Jun 29, 8.

An easier to read schematic: The opamp and its negative feedback will automatically adjust Q1 base current such that the voltage across sense resistor R5 is identical to the voltage across R4.
Dec 28, 9. Your beta assumptions are wrong. Here is a screen shot of the circuit, an explanation of my rationale, and the problem I am having. When the voltage datasheeh my sense resistor exceeds 4V, 4mA total current, the LMN will output low unbiasing the 2n By that logic my base current, 3. Dec 29, Could someone explain this section to me? I am pretty sure I’m interrupting the datasheet incorrectly. Dec 20, 10, 1, Sep 20, The output voltage is only guaranteed to be 3. Dec 27, 1.
Also, Vce is listed as 1V here.

The LMN does not go rail-to-rail so the output is 3. You have several problems. Beta is also dependent on Vce. You can omit the pm356n resistor. You didn’t show the entire datasheet page, but I think the DC gain of 70 is a minimum value for that collector current. In this case, something in the 1K to 10K range might help, but I wouldn’t put it in until needed. Mar 4, 2, Delete R1 for now. datsaheet
Dec 27, 2. AC gain confusion Posted by vustudent in forum: With that information I assumed I would reference the 3rd entry for the behavior I could expect. How I see it if I’m fully on, what would my collector current be? How does this factor in? I want to ensure 4mA collector current regardless of my load.

How can I implement this here? Aug 1, 7, 2, Thank you all so much for any input. As it stands right now, I get 2. Mar 30, 7, 1,
