LM358 Dual Low Power Operational-Amplifier IC (DIP)

LM358 Dual Low Power Operational-Amplifier IC (DIP)

The LM358 is a versatile dual low power operational-amplifier IC that integrates two high-gain, internally frequency-compensated op-amps in a single DIP package. It delivers reliable analog performance across a wide supply voltage range, making it a popular choice for hobbyists, students, and professional engineers.

Key Features

• Two independent operational amplifiers in one DIP package
• Internally frequency-compensated for stable operation without external compensation
• Wide supply voltage range: 3V to 32V (single supply) or ±1.5V to ±16V (dual supply)
• Low power consumption, suitable for battery-operated applications
• Large output voltage swing and high open-loop gain for accurate signal amplification
• Standard DIP footprint for easy breadboard and PCB mounting

Applications

• Signal conditioning and amplification
• Voltage comparators (for many general-purpose comparator tasks)
• Active filters and oscillator circuits
• General-purpose analog circuit building blocks
• Student labs, DIY electronics, prototyping and embedded projects

Why Choose the LM358 for Your Project

• Reliable performance across a broad supply range simplifies design choices
• Low quiescent current extends battery life in portable systems
• DIP package allows fast prototyping on breadboards and easy replacement on PCBs
• Widely available and cost-effective for classroom and production use

Typical Usage and Circuit Tips

• Use decoupling capacitors (0.1uF close to the supply pins) to improve stability and noise immunity
• Confirm supply voltage and common-mode input range in your design; the LM358 is optimized for single-supply operation
• For comparator-like functions, add hysteresis or a small positive feedback loop to prevent output oscillation
• Refer to the manufacturer datasheet for detailed pinout, timing, and absolute maximum ratings before layout and assembly

Package and Mounting

The LM358 is available in a standard DIP package that is breadboard-friendly and simple to solder on through-hole PCBs. Its footprint makes it ideal for rapid prototyping and educational kits.

Ordering and Compatibility

LM358 devices are manufactured by multiple semiconductor suppliers and are generally interchangeable, but always verify the datasheet for pinout and electrical characteristics when substituting parts. Images are for illustration purposes only.
