Understanding the lm358 Op Amp Module
The lm358 is a dual operational amplifier, meaning it contains two separate op amps within a single package. Each op amp is capable of performing various linear and non-linear operations, making it a versatile choice for a wide range of applications. The lm358 operates from a single supply voltage, typically between 3V and 32V, and consumes very low power, making it ideal for battery-powered devices.
One of the key features of the lm358 is its wide input common-mode voltage range, which allows it to work with signals that are close to the supply voltage. This makes it suitable for applications where the input signal may vary significantly. Additionally, the lm358 has a high input impedance, which ensures that it does not load the source circuit significantly, preserving the integrity of the input signal.
