Many of these devices are operated by non-tech-savvy users who may not know how to maintain their own device security. Feb 16, 2.

Aug 1, 7, 2, Your name or email address: 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.

View attachment Why does its output perform like this way, not dc voltage output?

That means, according to my calibrated eye, the valley is about 25 microsecond wide. The datasheet says the slew rate is 0.

Note that low power devices are usually slow speed devices. Posted by gaya3eeee in forum: 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 dxtasheet voltage around Posted by rezash in forum: Feb 6, 2.

Low Power Dual Operational Amplifiers

So, each valley is about 66 microSeconds apart at 15kHz. Why did you replace an emitter-follower pull up datashdet with a 47K resistor? How does this happen? Quote of the day. Do you already have an account? That means 13 microSeconds going down and 13 microseconds going up. View attachment Figure 4 Modified circuit Here is the modified circuit output, which is not my expectation.

I don’t know if this saturated and the top datazheet cut since this is very big output gain. Feb 16, 3. Can anyone tell me why the waveform is lean towards the back? After I modified the circuits, which Q1 was replaced with 47K resistor and I put diode between pin 7 and the base of Q3.

LMD Datasheet is attached. The output was as follows. Posted by Faizan Ahmad in forum: Yes, my password is: I have an original circuits as follows: Feb 18, 4. Thank you for your help. Digital Signal Processing in Scilab: Looking at your o-scope output, my calibrated dtasheet is fairly accurate and the datasheet is exactly right.

So, let’s take 13 microseconds 0. Feb 16, 1.

Also, what is the function of Q2 in this circuit?
