[IMSAI Guy] got some fake LM358 op-amps. Uncharacteristically, these chips actually performed well even though they didn’t act like LM358s. [IMSAI Guy] did a video about the fake chips and someone who ...

This is a circuit in which LED glows slowly in the beginning, then grows brighter and once again slowly it becomes dim. The basis of the whole circuit is an operational amplifier IC named LM358. This ...

Op amps are typically used to build signal processing circuits like amplifiers, integrators and oscillators. Their functionality can be described by mathematical formulas that have a single, ...
