LM258APE4

Overview

The LM258APE4 is a dual operational amplifier from the LM258A series manufactured by Texas Instruments. It features two independent high-gain amplifiers in an 8-pin PDIP package. Key electrical parameters include a gain-bandwidth product of 700 kHz, a slew rate of 0.3 V/µs, and a maximum input offset voltage of 3 mV. The device operates on a single power supply ranging from 3 V to 32 V or dual supplies of ±1.5 V to ±16 V. It draws a typical operating current of 350 µA per channel and provides an output short-circuit current capability of 20 mA.

Feature Summary

• Dual-channel architecture with rail-to-rail output capability for flexible signal handling
• Internal frequency compensation ensures stability without external components
• Wide single-supply voltage range supports diverse power environments
• Low quiescent current consumption suitable for battery-powered applications

Applications

• General-purpose analog signal conditioning circuits
• Transducer amplification interfaces
• Active filter designs
• Voltage comparators with hysteresis

Procurement Notes

Verify component authenticity through authorized distributors as counterfeit risks exist for legacy parts. Confirm RoHS compliance status via official datasheets. Check for obsolescence notices or lifecycle changes from Texas Instruments before finalizing procurement plans. Ensure packaging type matches design requirements.

Selection Notes

Select this component when dual op-amp functionality is required within a standard DIP footprint. Consider the LM258A series for improved offset voltage specifications compared to standard LM258 variants. Evaluate thermal performance and PCB layout constraints associated with the PDIP-8 package for optimal heat dissipation.

Part Context

The LM258A series represents an enhanced version of the industry-standard LM258 dual operational amplifier. The 'P' suffix indicates a plastic DIP package, while 'E4' denotes lead-free composition compliant with specific environmental standards. This part belongs to a long-standing family known for cost-effectiveness and widespread adoption in general-purpose electronics.

Replacement Considerations

Direct pin-compatible substitutes include LM258DRG4 and LM258D. Verify package compatibility and electrical parameter tolerances against original design specifications before substitution.
