lm358 IC (amplifier circuit) datasheet, characteristics, pins, working principle, application fields and alternative models
The LM358 IC is a very popular dual operational amplifier (Op-Amp). This model usually has different abbreviations such as lm386 ic, lm386 circuit, lm386 amplifier, lm386 amplifier circuit, etc.
The following is some basic information about it:
Manufacturer: Several companies make the LM358 op amp. It was originally designed by National Semiconductor, which was later acquired by Texas Instruments (TI).
But Texas Instruments isn't the only company making such chips. Others such as Fairchild, STMicroelectronics, ON Semiconductor, etc. also have their own versions.
