Description of ic components LM358W and LM358AW
Description about electronic component LM358W and LM358AW three follows:
one:These circuits consist of two independent, highgain,internally frequency- compensated which were designed specifically to operate from a single power supply over a wide range of voltages.
Two:The low power supply drain is independent of the magnitude of the power supply voltage.Application areas include transducer amplifiers, DC gain blocks and all the conventional op-amp circuits which now can be more easily implemented in single power supply systems. For example, these circuits can be directly supplied with the standard +5V which is used in logic systems and will easily provide the required interface ic components without requiring any additional power supply.
Three:In the linear mode the input common-mode voltage range includes ground and the output nvoltage can also swing to ground, even though operated from only a single power supply voltage.

Trend analysis of electronic components Industry
Industry has been increasing the electronic components package of China steadily, has brought up ten major China and capsulated enterprises too, but the electronic component Vice President of employer’s organization of China finishes gram and permits thinking, ten major this in China capsulates enterprises and still greatlies differ from each other compared with foreign company, especially international advanced packaging technique has already led a lot of, but we still remain at DIP and QFP stage.
So should in advanced to capsulate at the ic components technical development strengthening. In addition, he still appeals for speeding up the development of army and the people’s dual-purpose device one.

IC components lm358 General Description
The Ic components LM158 series consists of two independent, high gain,internally frequency compensated operational amplifierswhich were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.
If you learn more about ic components, recommend a site hqew.net, electronic components trading platform,many hard to find ic components besides lm358 on hqew.net.
