LM258H

Overview

The LM258H is a dual operational amplifier manufactured by Texas Instruments, housed in an 8-pin TO-99 metal can package. It features a gain-bandwidth product of 1 MHz and a slew rate of 500 mV/µs. The device operates within a supply voltage range of 3 V to 32 V. Key electrical specifications include a maximum input offset voltage of 2 mV, an input bias current of 45 nA, and a per-channel output current capability of 40 mA. It supports an operating temperature range from -25°C to 85°C.

Feature Summary

• Dual-channel general-purpose operational amplifier architecture
• High-speed performance with 1 MHz gain-bandwidth product
• Rail-to-rail output capability for extended dynamic range
• Robust metal can packaging for environmental stability

Applications

• Precision analog signal conditioning circuits
• Active filter implementations requiring high bandwidth
• Transducer amplification in industrial sensors
• Voltage comparison and buffering applications

Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with design requirements. Confirm that the TO-99-8 metal can package aligns with thermal and mechanical constraints. Check for any recent production change notices or obsolescence announcements directly from Texas Instruments before finalizing procurement plans.

Selection Notes

Select this component when high-speed dual amplification is required in a ruggedized form factor. The TO-99 package offers superior thermal dissipation compared to plastic variants. Ensure the 40 mA output current meets load requirements. Compare against LM258AD for lower offset voltage needs or LM258D for cost-sensitive surface-mount designs if the metal can is not mandatory.

Part Context

This part belongs to the LM258 family of dual operational amplifiers, known for their versatility in analog applications. The 'H' suffix specifically denotes the TO-99-8 metal can package variant, distinguishing it from standard plastic DIP or SOIC versions. It shares core electrical characteristics with other LM258 series members but provides enhanced physical durability and thermal performance suitable for demanding environments.

Replacement Considerations

• LM258H/NOPB
• LM258H/883B
