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

An easier to read schematic: No, create an account now. You have several problems. Dec 28, 5.

Dec lm356b, 1. Mar 14, 20, 5, Lastly, I’ve heard it is poor practice to use an op-amp as a comparator without some sort of hysteresis. With that information I assumed I would reference the 3rd entry for the behavior I could expect.

I’d like to make a few comments: 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. By that logic my lm356h current, 3. What exactly am I screwing up here? Dec 28, 7.

l,356n Dec 28, 8. Your name or email address: You only need 4mA, so beta isn’t a critical parameter. Hopefully, I was clear in my explanation. That will also help with the max output voltage. Quote of the day.

Could someone explain this section to me? I want to ensure 4mA collector current regardless of my load. Your beta assumptions are wrong.

DC current gain Posted by qitara in forum: Dec 27, 3. Most importantly, the opamp gain at DC is around , so that additional 70 doesn’t really figure datsheet the gain equations.

Dec 28, 6. Aug 1, 7, 2, You can omit the base resistor. Thank you all so much for any input. Beta is also dependent on Vce. Dec 29, When the voltage across my sense resistor exceeds 4V, 4mA total current, the LMN will output low unbiasing the 2n You May Also Like: Dec 27, 2.

Dec 28, As it stands right now, I get 2. 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.

Also can’t you turn off the “chicken pox” eatasheet Dc gain Posted by Yuvaloh1 in forum: Delete R1 for now. How I see it if I’m fully on, what would my collector current be?

Here is a screen shot of the circuit, an explanation of my rationale, and the problem I am having. Jun 29, 8. Dec 28, 4. The second key to this circuit is that the transistor emitter current equals to the collector current. Its purpose is to protect Q1 from too much base current, which is not a problem in this circuit.

The output voltage is only guaranteed to be 3.
