[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 so… ...

Figure 9 Test results when using one LM358 and a 100 k trimmer (C = 47 μF, R = 100k, R1= 100, T = 6.51 sec.) show that the real circuit works as expected. Implementing the circuit of Figure 6 allows ...

The LM358 datasheet specifies that it consists of two independent, high gain, internally frequency compensated operational amplifiers. ... I created this website and I want to invite you to ...

Using a LM358 as a non-inverting summing amplifier, ... His circuit is there to be able to add a VDC to the signal, to be able to shift it up or down as desired.

Anyway, I have just found TI app note dated as recently as January this year (2019) that delves into the design and use of the LM324 and the closely-related cousins: LM124, LM224, LM2902, LM158, LM258 ...
