What is LM348?
The LM348 is a quadruple, independent, high-gain, internally compensated operational amplifier designed to have operating characteristics similar to the µA741. It consists of four internal built-in amplifiers. The amplifier exhibits low supply-current drain and input bias and offset currents that are much less than those of the µA741.

LM348 Application
LM348 has four internal amplifiers. We can achieve isolation between these amplifiers by biasing each of the amplifiers independently. This isolation can be done using different techniques. It can be used at several different places where amplifier matching is needed.
LM348 vs. LM358
The LM348 is kind of a quad μA741, so it has a class AB output stage. The LM358/LM324 has a different kind of output stage that is more prone to crossover distortion.

Frequently Asked Questions
What is LM348?
LM348 is a general-purpose operational amplifier having four internal built-in amplifiers. It consists of four internal built-in amplifiers. These amplifiers are biased with a separate power supply and they can be isolated using the layout technique. It provides high gain.
What is the working principle of op-amp?
An operational amplifier is an integrated circuit that can amplify weak electric signals. An operational amplifier has two input pins and one output pin. Its basic role is to amplify and output the voltage difference between the two input pins.
Can LM258 replace LM348?
LM258 is a low-power dual operational amplifier that can be used for single-supply operation. LM348 is a quad operational amplifier with the same pin arrangement as LM324. LM324 is a chip that works with dual power supplies and is a combination of four 741 chips. The pin numbers of the two chips are not the same, so direct replacement is not possible. The replacement depends on the specific circuit of the redesign application.
