LM258DMR2G

Overview

The LM258DMR2G is a dual operational amplifier from onsemi, housed in an 8-MSOP package. It operates within a supply voltage range of 3.0 V to 32 V single supply or ±1.5 V to ±16 V split supplies. Key electrical characteristics include a gain-bandwidth product of 1 MHz, a slew rate of 600 mV/µs, and an input bias current of 45 nA typical. The device features short-circuit protected outputs, internally frequency compensation, and an operating temperature range of -25°C to +85°C.

Feature Summary

• True differential input stage with common mode range extending to the negative supply rail
• Short circuit protected outputs for enhanced reliability
• Internally compensated for stability in standard configurations
• ESD clamps on inputs increase device ruggedness

Applications

• Transducer amplifiers
• DC gain blocks
• Single supply logic system interface electronics

Procurement Notes

Verify the specific suffix DMR2 corresponds to the Micro8 (CASE 846A) package and tape & reel shipping configuration. Confirm RoHS compliance and Pb-free status as indicated by the G suffix or microdot marking. Ensure the ordering quantity aligns with the manufacturer's standard packaging unit of 4000 units per reel.

Selection Notes

Select this component for applications requiring low power drain independent of supply voltage magnitude. It is suitable for designs needing input common-mode voltage to include ground without external biasing. Consider the 8-MSOP footprint for space-constrained surface mount assemblies requiring dual op-amp functionality.

Part Context

This device belongs to the LM258 series, which utilizes circuit designs perfected for quad operational amplifiers. It serves as a dual-channel equivalent to one-half of an LM324. The series is designed for single supply operation, offering advantages over standard types by eliminating the need for external biasing components in many ground-referenced applications.
