2005年10月28日 · I have a circuit with a 1458 analog op amp that is powered with a single polarity supply of 12 volts. The first stage (pin 3) of the circuit has incoming pulses that go …

2015年11月3日 · That said, it could sort of work. What you would do is put a capacitor of 10 - 100 uF between the output and the speakers. You would also put capacitors of perhaps 1 uF …

2020年12月31日 · LM358 and 1458 are similar but have different output stage. TL082 has FET input stage with class AB output ...

2015年4月22日 · VCO with LM1458 op amp Home. Forums. Hardware Design. General Electronics Chat. VCO with LM1458 op amp ...

2005年11月6日 · Does anyone out there know how I might get the positive and negative supply voltage required to power a 741 or 1458 op amp from a transformer that is not center tapped? …

2012年1月30日 · The op amp used is a general-purpose op amp, such as the 1458 or 741. General-purpose op amps have typical slew rates of 0.5 V/ ￿ s and gain-bandwidth …

2010年11月13日 · I am trying to fix my Tek scope power -8 and -15 power supply. I suspect that the op amp in the circuit is bad. It is a C1485C. I do not have one on hand but the Shack has …

2014年8月10日 · This seems simple from what I've read, but having problems. Trying to use a 741 op amp to compare two voltages. I need to be able to compare voltages between 1 and 3 …

2017年11月2日 · But if the op amp circuit has any negative feedback, it will change it to positive feedback and the circuit then will likely oscillate or latch up at one of the rails. Reactions: …

2024年3月7日 · I am wondering if possible to find an op-amp with high output current up to 600 mA. We have +/- 5 V available for biasing of the op-amp but the load requirement is 600 mA …
