LM258DRG4

Overview

The LM258DRG4 is a dual general-purpose operational amplifier manufactured by Texas Instruments. It features two independent amplifiers within a single 8-SOIC package. 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. Key electrical specifications include a gain-bandwidth product of 700 kHz and a slew rate of 0.3 V/µs. Supply current per channel is typically 500 µA, with a maximum output current of 40 mA per channel. Input offset voltage is specified at 3 mV, and input bias current is 20 nA. The component supports surface-mount installation and functions within an ambient temperature range of -25°C to 85°C.

Feature Summary

• Dual-channel architecture providing two independent operational amplifiers in a compact surface-mount package
• Single-supply operation capability spanning 3 V to 32 V for versatile system integration
• Low quiescent current consumption of 500 µA per channel for energy-efficient designs
• Internal frequency compensation ensures stability without external components

Applications

• Transducer amplification
• DC gain blocks
• Active filters

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and environmental compliance status. Ensure the procurement source provides valid traceability records. Confirm that the delivered units match the exact part number designation to avoid functional discrepancies related to manufacturing revisions or regional variations.

Selection Notes

Select this component when a low-cost, dual-channel solution is required for single-supply applications. The wide common-mode input voltage range extending to ground makes it suitable for interfacing with various sensors. Consider the 700 kHz bandwidth limit for signal processing requirements. Evaluate thermal performance within the SOIC package for high-density PCB layouts.
