2010年12月6日 · 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 …

2006年3月25日 · The LM324 produces an annoying buzzing 0.3% crossover distortion when it has NO gain, when all its gain is used as negative feedback to try to reduce its crossover …

2009年2月10日 · The LM324 and LM358 have outputs that work at the negative supply voltage but do not work if they are higher than 1.5V less than the positive supply voltage. Some …

2011年8月29日 · Did you also download the LM324.mod file on that yahoo link, I just downloaded the unis and .mod and it works ok without any other actions. Make sure the LM324.mod is in …

2009年3月16日 · 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 …

2011年5月22日 · Any opamp will work but the LM324 quad or the LM358 dual are nice because they work when the supply is only 3.0V. The circuit is missing parts that control the output …

2010年5月25日 · The LF347 has at least twice the bandwidth of the LM324, requires 1000 times less input bias current (higher input impedance), slew rate 10 to 20 times faster, among other …

2009年7月7日 · A load resistor would be connected from the output pin of the LM324 to either ground or +10V. I seem to remember (audiguru will chime in on this) that an LM324 is a …

2025年3月10日 · 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 …

2010年11月7日 · I placed the two of them in the same breadboard. The input (+) connected on the LM324 was an IR receiver module. I used a transistor symbol because I can't find one IR …
