741 op-amp

Hello AAC, I want to design a low pass filter with a cutoff frequency of 100Hz that would take a 150Hz input. The first photo is my simulation schematic, and the second has the bode plots from the AC sweep analysis. I didn't expect the roll-off to look like that, so I thought I might be doing...

Hello AAC, I have a laboratory requirement about making a circuit with the following characteristics: With good variety of components (Say, 12 unique components, but there is no specific number) With 741/358 and/or a 555 timer With 3 analog sensing elements (Say, a LDR) No microcontrollers No...

I'm boosting a square signal (non uniform) with op-amp LM-741C. Supply voltage is variable up to 30 volts to control the amplitude of the output signal. The circuit was working fine for many months now and I was getting the output signal up to 27 volts p-p. Suddenly the output dropped and I can...

Hi, I need some help here, I want to calculate the maximum operating frequency that will not cause distortion in my output signal due to slew rate characteristics, for the ampop lm741, for example if I have 1 Volt amplitude in my input and I have a gain af=20dB (linear 10) and another case if I...

So, i want to use an Op Amp with inverting topology to invert -3,3v into 3.3v (gain of -1). when i simulated it as in the figure i've used single power supplies and it worked (even with 5v in simulation). But in the practice i've tried 5v,12v and 15v single power supplies and none of them made...

Hi, I am trying to plot frequency response of 741 op-amp by LTSpice. No matter I tried, I can't get the plot to be shown. I am a newbie as I just started with LTSpice yesterday. I have attached the file below, please help me to inspect what did I do wrong. Thank you so much.
