LM358N: A Powerful Yet Budget-Friendly Operational Amplifier

The LM358N is the most commonly used operational amplifiers in the world of analog electronics. It is a general purpose single supply (operational amplifier/OP-AMP) It is the most common ic for use in factors like non-inverting Somparator, PWM generator and many other where high gain is required. There are various different op-amps available, but one of the most common is the LM358N IC due to its low cost, simplicity and great performance. Here we will learn How LM358N works,What are the lm358n features, How you use LM358N with the help of LM358N amplifier circuit, LM358N datasheet ST, etc. We'll also go over the comparison between LM358N vs LM358P vs LM358AN.

What is LM358N?

The LM358N is a dual, high-gain, internally frequency-compensated operational amplifier IC which consist of two independent, high-gain, frequency-compensated op-amps. It is one of the most common components used throughout the electronics industry .One of its most prominent features is that it simplifies the connection with a single power supply, and also it can work at a voltage of 3V to 32V making it possible to run in operating conditions, especially low-voltage systems, such as arduino (LM358N arduino).

LM358N Features

■ Internally frequency-compensated
■ Large DC voltage gain: 100 dB
■ Wide bandwidth (unity gain): 1.1 MHz(temperature compensated)
■ Very low supply current per operatoressentially independent of supply voltage
■ Low input bias current: 20 nA(temperature compensated)
■ Low input offset voltage: 2 mV
■ Low input offset current: 2 nA
■ Input common-mode voltage range includesnegative rails
■ Differential input voltage range equal to thepower supply voltage
■ Large output voltage swing 0 V to (VCC+ -1.5 V)

LM358N vs LM358P vs LM358AN – What's the Difference?

They say: LM358N vs LM358P or LM358N vs LM358AN … are there actually any technological differences? Functionally, they are almost equivalent. The differences are primarily in the packaging, and in the manufacturer-specific values:
LM358P: Usually plastic DIP, found in cost sensitive designs.
LM358AN: Provides better spec control and performance on noise and temperature range.
LM358N: The ordinary and commonly used version for general use.
Although they are small, such differences may have a significance in practical high-precision work. However, in most hobby and DIY applications, they are more or less interchangeable.

LM358N Manufacturers: ST, TI,Fairchild, Motorola, CHN

The most common version in the market is ST. It offers high quality and stability at a reasonable price and is widely used in industrial and consumer electronics. Other TI brands have also stopped supplying reliable versions. Fairchild LM358N and Motorola LM358N are also reputable variants, especially useful in industrial or replacement needs. You can find multiple versions online, and check the datasheet (datasheet LM358N) from various manufacturers, including CHN LM358N datasheet or National Semiconductor LM358N datasheet.
