LM358 Operational Amplifier — Datasheet & Specifications

The LM358 is a general-purpose dual op-amp widely used for signal amplification, filtering, comparator circuits, oscillator designs, sensor signal conditioning, and analog mathematical operations. Its wide supply voltage range and low power consumption make it suitable for industrial control, instrumentation front-ends, consumer electronics, and telecommunications signal-processing circuits.

The LM358 can be used in basic audio amplification circuits but is not considered ideal for high-fidelity audio applications. Its relatively limited bandwidth (around 1 MHz unity-gain) and higher noise compared to dedicated audio op-amps make it better suited for non-critical audio tasks. For precision audio design, consider specialized audio op-amp ICs from manufacturers like ROHM or National Semiconductor.

The LM358 operates on a single supply voltage ranging from 3V to 32V, or on dual supplies from ±1.5V to ±16V. This wide operating range makes it highly versatile, allowing integration into battery-powered devices, industrial equipment, and systems using standard 5V, 12V, or 15V rails without requiring additional regulation.

Commercial-grade LM358 ICs are rated for the standard 0°C to +70°C temperature range and are used in general consumer and industrial electronics. Military-spec (Mil-spec) variants meet stricter standards for temperature range (typically -55°C to +125°C), reliability screening, and traceability, making them suitable for defense, aerospace, and harsh-environment industrial applications.

LM358 op-amps are produced as industry-standard second sources by multiple manufacturers, including National Semiconductor (now Texas Instruments), AMD, ROHM, Philips Semiconductors, Burr-Brown, and Elantec. LEVEL SOLUTIONS sources genuine components from all these manufacturers in commercial and Mil-spec grades, ensuring broad availability for design and procurement engineers.

The LM358 is available in a wide range of package types, including DIP-8, SOIC-8, SOP-8, TSSOP-8, and SOT-23 variants, depending on the manufacturer. LEVEL SOLUTIONS offers all package types across multiple manufacturers, enabling engineers to source the exact footprint required for their PCB layout and production requirements.
