Dec 28, 6. You didn’t show the entire datasheet page, but I think the DC gain of 70 is a minimum value for that collector current. Quote of the day. DC current gain Posted by qitara in forum: Dec 27, 2. Aug 1, 7, 2, If you have 3. Dc gain Posted by Yuvaloh1 in forum: As it stands right now, I get 2.

What exactly am I screwing up here? You can omit the base resistor. Dec 29, My Rationale Using the datasheet, to the best of my ability, it looks like my DC current gain would be How can I implement this here?

Could someone explain this section to me? Dec 20, 10, 1, Delete R1 for now. Dec 28, 7. Dec 28, 5. 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. With that information I assumed I would reference the 3rd entry for the behavior I could expect.

Mar 4, 2, I know I may have to implement some hysteresis into this circuit. AC gain confusion Posted by vustudent in forum: No, create an account now. When the voltage across my sense resistor exceeds 4V, 4mA total current, the LMN will output low unbiasing the 2n Use a ohm resistor for Rsense and set the voltage divider to give you 0.

Sep 20, Dec 28, 8. Hopefully, I was clear in my explanation. Beta is also dependent on Vce. Lastly, I’ve heard it is poor practice to use an op-amp as a comparator without some sort of hysteresis.

Dec 28, Both serial connections and USB to serial conversion ratasheet are covered. The LMN does not go rail-to-rail so the output is 3.

Also can’t you turn off the “chicken pox” dots?? By that logic my base current, 3. 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 correctly.

How I see it if I’m fully on, what would my collector current be? Hope this helped, Kevin. I want to lm356m 4mA collector current regardless of my load. It should not be used a design parameter for several reasons. Dec 27, 1. The output voltage is only guaranteed to be 3.

Thank you all so much for any input. You only need 4mA, so beta isn’t a critical parameter.

Mar 14, 20, 5, To avoid these issues, you can change your voltage divider to use a voltage below the guaranteed max input voltage.
