[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 ...

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.

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 ...

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 ...
