To avoid these issues, you can change your voltage divider to use a voltage below the guaranteed max input voltage. Dec 29, It should not be used a design parameter for several reasons.

Yes, my password is: Jun 29, datwsheet. Dec 20, 10, 1, Here is a screen shot of the circuit, an explanation of my rationale, and the problem I am having. Sep 20, Beta is also dependent on Vce. Mar 14, 20, 5, 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.

Dec 27, 1. How I see it if I’m fully on, what would my collector current be? Dec 27, datasheett. With that information I assumed I would reference the 3rd entry for the behavior I could lm365n. Dec 27, 3. The second key to this circuit is that the transistor emitter current equals to the collector current. Lastly, I’ve heard it is poor practice to use an op-amp as a comparator without some sort of hysteresis.

I am trying to setup a constant current source using a 2n and a Motorolla LMN.

I want to ensure 4mA collector current regardless of my load. Do you already have an account? How can I implement this here? I am pretty sure I’m interrupting the datasheet incorrectly. Dec 28, 4. The output voltage is only guaranteed to be 3.

The LMN does not go rail-to-rail so the output is 3. Both serial connections and USB to serial conversion connections are covered. Mar 4, 2, No, create an account now. Mar 30, 7, 1, AC gain confusion Posted by vustudent in forum: In this case, something in the 1K to 10K range might help, but I wouldn’t put it in until needed. My Rationale Using the datasheet, to the best of my ability, it looks like my DC current gain would be If you have 3.

Dc gain Posted by Yuvaloh1 in forum: Most importantly, the opamp gain at DC is around , so that additional 70 doesn’t really figure into the gain equations.

Also can’t you turn off the “chicken pox” dots?? You have several problems. Dec 28, 8. 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.

Could someone explain this section to me? Use a ohm resistor for Rsense and set the voltage divider to give you 0. I know I may have to implement some hysteresis into this circuit.

Your beta assumptions are wrong. Aug 1, 7, 2, You can omit the base resistor. When the voltage across my sense resistor exceeds 4V, 4mA total current, the LMN will output low unbiasing the 2n How does this factor in? Your name or email address:
