LM358 Operational Amplifier IC

Dual Op-Amp: The LM358 contains two separate op-amps, often labeled as A and B. Each op-amp can be used independently for various analog signal processing tasks.

General-Purpose Op-Amp: The LM358 is a general-purpose op-amp suitable for a wide range of applications, including amplification, filtering, voltage following, and comparator functions.

Single-Supply Operation: The LM358 is designed to operate from a single positive power supply voltage (typically +3V to +32V). This feature makes it compatible with many battery-powered and single-supply applications.

Low Power Consumption: The LM358 has low power consumption, making it suitable for battery-powered devices and applications where energy efficiency is essential.

Input and Output Ranges: The input voltage range for the LM358 typically includes the entire range between the supply voltage and ground. The output voltage can also swing close to the supply voltage and ground.

Common-Mode Input Range: The common-mode input voltage range, which is the range of input voltages where the op-amp operates within its specifications, typically includes ground (0V) as a reference.

Differential Input: Each op-amp within the LM358 has two input terminals, an inverting (-) and a non-inverting (+) input. The voltage difference between these terminals (differential input) determines the op-amp's response.

Open-Loop and Closed-Loop Operation: The LM358 can be used in open-loop configurations for simple amplification or in closed-loop configurations, such as inverting and non-inverting amplifiers, to achieve specific gain and filtering functions.

Applications: The LM358 is used in various applications, including audio amplifiers, signal conditioning, voltage followers, active filters, and comparator circuits.
