It should not be used a design parameter for several reasons. By that logic my base current, 3. I want to ensure 4mA collector current regardless of my load. Why does your schematic drawing software produce backwards negative white lines on a black background instead of a normal positive image?? Dc datasheft Posted by Yuvaloh1 in forum: DC current gain Posted by qitara in forum: AC gain confusion Posted by vustudent in forum: Use a ohm resistor for Rsense and set the voltage divider to give you 0.
Dec 27, 3. Mohn Use a ohm resistor for Rsense and set the voltage divider to give you 0. To avoid these issues, you can change your voltage divider to use a voltage below the guaranteed max input voltage. Quote of the day. Dec 28, 5. Dec 28, 9. I am trying to setup a constant current source using a 2n and a Motorolla LMN.
If you have 3. Jun 29, 8. Mar 30, 7, 1, Delete R1 for now. An easier to read schematic: It should not be used a design parameter for several reasons. You have several problems. The output voltage is only guaranteed to datashfet 3. Yes, my password is: Dec 28, 6. AC gain confusion Posted by vustudent in forum: Both serial connections and USB to serial conversion connections are covered.
Hopefully, I was clear in my explanation. The LMN does not go rail-to-rail so the output is 3. Dec 29, Sep 20, With that information I assumed I would reference the 3rd entry for the behavior I could expect.
Mar 4, 2, Your name or email address: You can omit the base resistor. Here is a screen shot of the circuit, an explanation of my rationale, and the problem I am having. That will also help with the max output voltage. Also, Vce is listed as 1V here. No, create an account now. My Rationale Using the datasheet, to the best of my ability, it looks like my DC current gain would be Your beta assumptions are wrong. Dec 20, 10, 1, Depending on the value of the sense resistor there is a chance that the opamp output might not be able to swing low enough to drive Q1 datadheet.
Mar 14, 20, 5, Dec 28, 8. When the voltage across datsheet sense resistor exceeds 4V, 4mA total current, the LMN will output low unbiasing the 2n What exactly am I screwing up here? Shaktikora I know I may have to implement some hysteresis into this circuit. AC gain confusion Posted by vustudent in forum: Do you already have an account? Yes, my password is: My Rationale Using the datasheet, to the best of my ability, it looks like my DC current gain would be Both serial connections datashewt USB to serial conversion connections are covered.
