So, each valley is about 66 microSeconds apart datashewt 15kHz. 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 18, 4.

Can anyone tell me what this cable assy is for? The datasheet says the slew rate is 0. Yes, my password is: Feb 16, lm258e. How does this happen?

That means 13 microSeconds going down and 13 microseconds going up. Your name or email address: You May Also Like: Digital Signal Processing in Scilab: Thank you for your help.

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. I have an original circuits as follows: You need a slower Pwm frequency or a faster op amp. Posted by daatsheet in forum: Can anyone tell me why the waveform is lean towards the back?

Aug 1, 7, 2, Feb 16, 2. Looking at your o-scope output, my calibrated eye is fairly accurate and the datasheet is exactly right. Also, what is the function of Q2 in this circuit?

Posted by sarkarnov in forum: View attachment Figure 4 Modified circuit Here is the modified circuit output, which is not my expectation. LMD Datasheet is attached. Posted by Faizan Ahmad in forum: Many of these devices are operated by non-tech-savvy users who may not know how to maintain their own device security. Feb 6, 2. That means, according to my calibrated eye, the valley is about 25 microsecond wide.


No, create an datasheef now.

Do you already have an account? Quote of the day. The output was as follows. Why did you replace an emitter-follower pull up device with a 47K resistor?

Posted by rezash in forum: Feb 16, 1. After I modified the circuits, which Q1 was replaced with 47K resistor and I put diode between pin 7 and the base of Q3.

View attachment Why does its output perform like this way, not dc voltage output? I don’t know if this saturated and the top was cut since this is very big output gain. So, let’s take 13 microseconds 0. Nov 23, 8, 6, Note that low power devices are usually slow speed devices.
