After I datqsheet the circuits, which Q1 was replaced with 47K resistor and I put diode between pin 7 and the base of Q3. How does this happen?

Feb 6, 2. Your name or email address: Why did you replace an emitter-follower pull up device with a 47K resistor? Also, what is the function of Q2 in this circuit? Posted by gaya3eeee in forum: I don’t know if this saturated and the top was cut since this is very big output gain. Quote of the day.


Can anyone tell me why the waveform is lean towards the back? That means 13 microSeconds going down and 13 microseconds going up.

Many of these devices are operated by non-tech-savvy users who may not know how to maintain their own device security. This is a very large increase in output impedance, and introduces a phase shift and low pass filter into the second opamp’s feedback loop. Can anyone tell me what this cable assy is for?

I have an original circuits as follows: Feb 16, 2. datwsheet

Yes, my password is: The datasheet says the slew rate is 0. So, each valley is about 66 microSeconds apart at 15kHz. You need a slower Pwm frequency or a faster op amp.

The output was as follows. No, create an account now. Aug 1, 7, 2, So, let’s take 13 microseconds 0. View attachment Figure 4 Modified circuit Here is the modified circuit output, which is not my expectation.
