The second key to this circuit is that the transistor emitter current equals to the collector dataxheet. Delete R1 for now. Also can’t you turn off the “chicken pox” dots??
2n3904 DC current gain confusion
Mar 30, 7, 1, How can I implement this here? Beta is also dependent on Vce. Dec 28, 5. Sep 20, Hope this helped, Kevin. Your name or email address: Both serial connections and USB to serial conversion connections are covered.
Mar 4, 2, You have several problems. Dc gain Posted by Yuvaloh1 in forum: When the voltage across my sense resistor exceeds 4V, 4mA total current, the LMN will output low dataheet the 2n Dec 27, 3. Could someone explain this section to me? Thank you all so much for any input.

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. AC gain confusion Posted by vustudent in forum: Jun 29, 8. No, create an account now. With that information I assumed I would reference the 3rd entry for the behavior I could expect. Its purpose is to protect Q1 from too much base current, which is not a problem in this circuit.
Also, Vce is listed as 1V here. It should not be used a design parameter for several reasons. I am pretty sure I’m interrupting the datasheet incorrectly. An easier to read schematic: I know I may have to implement some hysteresis into this circuit.
In this case, something in the 1K to 10K range might help, but I wouldn’t put it in until needed. To avoid these issues, you can change your voltage divider to use a voltage below the guaranteed max input voltage. That will also help with the lm35n output voltage.
I want to ensure 4mA collector current regardless of my load. Dec 27, 1.

Most importantly, the opamp gain at DC is around , so that additional 70 doesn’t really figure into the gain equations. What exactly am I screwing up here? Dec 28, 4. Here is a screen shot of the circuit, an explanation of my datxsheet, and the problem I am having. Your beta assumptions are wrong. The output voltage is only guaranteed to be 3.
My Rationale Using the datasheet, to the best of my ability, it looks like my DC current gain would be Mar 14, 20, 5, The LMN does not go rail-to-rail so the output is 3. Dec 28, How I catasheet it if I’m fully on, what would my collector current be?
