Aug 29, 2011 · i have downloaded LM324_unisym_test from yahoo groups **broken link removed**, and it is .asc file, when i click the icon it opens itself in LT spice and says "LM324 …

Dec 6, 2010 · The datasheets for the LM324 quad opamp and LM358 dual opamp show a VCO circuit that goes from a very low frequency growl to a fairly high audio pitch. An MC34074 …

Nov 7, 2011 · Is an LM324 a good replacement for an LM3900? I couldn't locate one of the latter so relayed my circuit to use an LM324 instead, well it doesn't work, i checked my output from …

Jun 25, 2013 · The LM324 is only compensated for unity gain, so it's very likely to oscillate. You will either have to increase the gain, or else add additional compensation. Click to expand...

May 4, 2019 · I checked the power supply for oscillations using the attached schematic for generating a square wave signal. I used as a load a 4.7R resistor rated at 5W. I used 1N4007 …

Mar 25, 2006 · The LM324 is the industry's first "low power" opamp so they made the output transistors without bias current. Therefore they produce horrible crossover distortion with audio …

May 25, 2010 · So what are the big differences/similarities between LM324 and LF347 Op-amps? I just want to understand them a bit more, and it would be great if someone can help.

Feb 12, 2008 · I once had a diagram to built a Voltage Control Oscillator out of a LM324. I dont found it anywhere. I try to google without luck. Anyone got a LM324 VCO circuit and shared it …

Feb 10, 2009 · I admit that this thread title is just to get attention and suggestions from Audioguru, that hates LM324. :) I too hate LM324 but ... but it was a nice device at its times. A lot of years …

Mar 10, 2025 · A pcb made according to the schematic (attached below) uses LM324 opamps. With no input signal to the current transformer pin 3 should be low, and pin 2 follows feedback …
