I have an original circuits as follows: Posted by sarkarnov in forum: You May Also Like: How does this happen? No, create an account now. Feb 18, 4. Nov 23, 8, 6, Note that low power dataheet are usually slow speed devices.

Why did you replace an emitter-follower pull up device with a 47K resistor? The output was as follows.

Yes, my password is: Your name or email address: After I modified the circuits, which Q1 was replaced with 47K resistor and I put diode between pin 7 and the base of Q3. Also, what is the function of Q2 in this circuit? View attachment Figure 4 Modified circuit Here is the modified circuit output, which is not my expectation.

Looking at your o-scope output, my calibrated eye is fairly accurate and the datasheet is exactly right. Feb 16, 1.

So, let’s take 13 microseconds 0. Do you already have an account? This is a very large increase in output impedance, and introduces a phase km258d and low pass filter into the second opamp’s feedback loop.


Can anyone tell me what this cable assy is for? Posted by gaya3eeee in forum: View attachment Why does its output perform like this way, not dc voltage output? Posted by Faizan Ahmad in forum: Quote of the day.

Posted by rezash in forum: I don’t know if this saturated and the top was cut since this is very big output gain. Many of these devices are operated by non-tech-savvy users who may not datasheet how to maintain their own device security.


Digital Signal Processing in Scilab: The datasheet says the slew rate is 0.

That means, according to datasyeet calibrated eye, the valley is about 25 microsecond wide. Can anyone tell me why the waveform is lean towards the back? So, each valley is about 66 microSeconds apart at 15kHz.

You need a slower Pwm frequency or a faster op amp. View attachment Figure 3 flyback circuit provides power input for the circuit in Figure 2 When I measured the pin 7 output at its original circuit in Figure 1, its output is dc voltage around Feb 6, 2. Feb 16, 3. Thank you for your help. Aug 1, 7, 2, That means 13 microSeconds going down and 13 microseconds going up.
