Rosfix LM358 – dual-channel operational amplifier

The LM358 is one of the most popular analogue integrated circuits. It contains two independent operational amplifiers in one package and works over a wide supply voltage range of 3 to 32 V, including single-supply operation. The package contains two pieces.

Key features

• two amplifier channels in one chip,
• low current consumption, useful in battery-powered devices,
• standard pinout, easy to swap into existing projects,
• stable operation in analogue circuits.

Applications

Analogue integrated circuits of this type are used in active filters, sensor signal amplifiers, comparators, regulators and simple audio preamplifiers. Thanks to the popularity of the LM358, you can easily find schematics and application examples online.

It is a practical component for hobby electronics enthusiasts and service technicians that is worth keeping in a drawer. Two pieces let you build several simple circuits or keep one as a spare.

The chip can be powered with a dual or single supply, and the inputs have a range that includes ground, which makes it easier to build simple sensor signal amplifiers. Before installation, it is worth consulting the LM358 datasheet to choose the gain resistors.
