LM258ADRE4

Overview

The LM258ADRE4 is a dual operational amplifier manufactured by Texas Instruments, belonging to the LM258A series. It features two independent high-gain amplifiers within an 8-SOIC surface-mount package. Key electrical specifications include a gain-bandwidth product of 700 kHz and a slew rate of 300 mV/us. The input offset voltage is specified at 3 mV with an input bias current of 20 nA. It operates on a single power supply ranging from 3 V to 32 V or dual supplies from 1.5 V to 16 V. The device draws 500 µA of supply current across both channels and provides a per-channel output current of 40 mA.

Feature Summary

• Dual-channel architecture providing two independent high-gain amplifiers in a compact surface-mount package.
• Rail-to-rail output capability allowing signal swing close to the supply rails for maximum dynamic range.
• Low quiescent current consumption suitable for battery-powered applications and energy-efficient designs.

Applications

• General-purpose analog signal conditioning circuits
• Transducer amplification interfaces
• Active filter implementations

Procurement Notes

Verify the specific suffix 'E4' against the manufacturer's official documentation to confirm RoHS compliance status and material composition changes. Confirm that the RE4 designation corresponds to the tape-and-reel packaging format rather than tube packaging. Ensure the component source matches Texas Instruments directly or through authorized distribution channels to avoid counterfeit parts.

Selection Notes

Select this component when a dual op-amp with rail-to-rail output is required alongside low power consumption. Compare the 3 mV input offset voltage and 700 kHz bandwidth against application requirements. Verify that the 8-SOIC package dimensions fit the PCB layout constraints. Consider the operating temperature range and supply voltage limits relative to the target system environment.

Part Context

This part belongs to the LM258 family of dual operational amplifiers, which are industry-standard general-purpose devices. The LM258A variant typically offers tighter performance specifications compared to standard versions. The LM258DRG4 serves as a related alternative within the same functional family, often sharing similar pinouts and electrical characteristics while differing in packaging or compliance markings.
