LM258DR

Overview

The LM258DR is a dual-channel operational amplifier manufactured by UMW, housed in an 8-SOP package. It features two independent high-gain amplifiers capable of operating from single or dual power supplies. Key electrical parameters include a gain-bandwidth product of 700 kHz and a slew rate of 0.3 V/µs. The input offset voltage is typically 2 mV, with an input bias current of 20 nA. It supports a supply voltage range of 3 V to 30 V (single) or ±1.5 V to ±15 V (dual). The device operates within a temperature range of -25°C to 85°C and provides an output short-circuit current capability.

Feature Summary

• Dual independent high-gain operational amplifiers
• Compatible with single or dual power supply operation
• Internal frequency compensation for stability
• Short-circuit protection on outputs

Applications

• General-purpose analog signal processing
• Transducer amplifiers
• Active filters
• Buffer amplifiers

Procurement Notes

Verify the manufacturer marking 'UMW' on the component body to distinguish it from other vendors like Texas Instruments or onsemi. Confirm the suffix 'DR' indicates the SOIC-8 tape-and-reel packaging format. Ensure the datasheet matches the specific revision required for your design constraints. Cross-reference pinouts if substituting from different manufacturers as minor variations may exist.

Selection Notes

Select this component when a cost-effective dual op-amp is needed for general-purpose applications. It is suitable for designs requiring operation from low-voltage single supplies up to 30 V. Consider the 700 kHz bandwidth and 0.3 V/µs slew rate limits for speed requirements. The SOIC-8 package is appropriate for surface-mount assembly processes.

Part Context

The LM258 series is a widely used industry-standard dual operational amplifier. The LM258DR variant specifically refers to the UMW production in an 8-pin Small Outline Package (SOIC). It serves as a direct functional replacement for the classic LM158/LM258/LM358 family, offering similar performance characteristics across various industrial and commercial temperature ranges.

Replacement Considerations
