LM358 OP AMP Introduction

Lm358 is a dual operational amplifier IC, which integrates two operational amplifiers powered by general electric source. It can be regarded as half of LM324 four channel operational amplifier, which contains four Operational Amplifiers with common power supply.

What is LM358 OP-AMP

Lm358 operational amplifier belongs to a low-power dual operational amplifier, including two independent, high gain, internal frequency compensation operational amplifiers, which are specially designed to work from a single power supply in a wide range of voltage. Lm358 adopts the micro SMD packaging technology of national semiconductor of the United States, and adopts chip size packaging (8-solder ball micro SMD). The shunt power supply can also work. The current consumption of the low power supply is independent of the power supply voltage.

If you want a simple switchgear for medium power loads, then 2N3055 is preferred. 2N3055 is one of the basic tLm358 operational amplifier has the characteristics of low power consumption, common mode input voltage range extended to ground / VEE and single power or separate power operation. Compared with standard operational amplifiers in single power applications, it has several obvious advantages. The amplifier can operate at a supply voltage as low as 3.0 V or as high as 32 v. The common mode input range includes a negative power supply, eliminating the need for external bias components in many applications. The output voltage range also includes a negative supply voltage.

How does a LM358 OP AMP work?

As mentioned before, Lm358 is a dual operational amplifier IC, which integrates two operational amplifiers powered by general electric source. It can be regarded as half of LM324 four channel operational amplifier, which contains four Operational Amplifiers with common power supply. The differential input voltage range can be equal to the supply voltage range. The default input offset voltage is very low, 2mV. The typical supply current independent of the supply voltage range is 500uA, and the maximum current is 700ua. At ambient temperature, the operating temperature range is 0 ° C to 70 ° C, and the maximum junction temperature can be as high as 150 ° C.
