LM258DMR2

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 150 nA maximum. The device features short-circuit protected outputs, low power drain with quiescent currents around 1.2 mA, and an input common mode voltage range extending to the negative supply rail.

Feature Summary

• True differential input stage allows common mode voltage range to extend to the negative supply, eliminating external biasing components in many single-supply applications.
• Outputs are internally short-circuit protected against ground faults, enhancing device ruggedness without affecting normal operation.
• Internally compensated design simplifies circuit implementation by ensuring stability across standard feedback configurations.
• ESD clamps integrated on inputs increase device ruggedness while maintaining signal integrity.

Applications

• Transducer amplifiers
• DC gain blocks
• Active filters

Procurement Notes

Verify the specific suffix 'DMR2' corresponds to the Micro8 (MSOP) package and industrial temperature range (-25°C to +85°C). Confirm RoHS compliance and Pb-free status as indicated by the 'G' suffix in related ordering information. Ensure the application environment does not exceed the maximum junction temperature of 150°C during operation.

Selection Notes

Select this component for general-purpose analog signal processing where low power consumption and single-supply operation are required. The wide common-mode input range including ground makes it suitable for battery-powered systems. Consider thermal dissipation if operating near maximum supply voltages with heavy loads.

Part Context

This device belongs to the LM258/LM358 family of single-supply dual operational amplifiers. It shares architectural similarities with quad amplifiers like the LM324 but contains two independent amplifiers per package. The series is designed to offer advantages over standard op-amps in single-supply applications due to its ability to handle input signals down to the negative rail.
