LM258DG

Overview

The LM258DG is a dual operational amplifier manufactured by onsemi, housed in an 8-lead Small Outline Package (SOIC). It features internally frequency-compensated high-gain amplifiers designed for single-supply operation. Key electrical parameters include a supply voltage range of 3V to 32V, a unity-gain bandwidth of 1.1MHz, and a slew rate of 0.6V/µs. The device offers low input bias current of 20nA and low input offset voltage of 2mV. It supports rail-to-rail output swing down to ground and operates within a temperature range of -40°C to +85°C.

Feature Summary

Internally frequency compensated for stability without external components
Single-supply operation capability with input common-mode range including ground
Low power consumption independent of supply voltage magnitude
Rail-to-rail output voltage swing extending to the negative rail

Applications

Transducer amplifiers
DC gain blocks
Interface electronics for logic systems

Procurement Notes

Verify the specific manufacturer designation as onsemi sources typically utilize suffixes such as DG or DMR2G for SOIC variants. Confirm active status and RoHS compliance through official datasheets, as legacy LM258 parts may have varying lifecycle statuses across different production eras. Ensure package dimensions match the target PCB footprint.

Selection Notes

Select this component when single-supply operation from standard logic voltages is required. The internal frequency compensation simplifies circuit design compared to uncompensated alternatives. Consider the 1.1MHz bandwidth and 0.6V/µs slew rate for moderate-speed signal processing applications requiring low power dissipation.

Part Context

This part belongs to the LM258 family of dual low-power operational amplifiers. It shares functional characteristics with other industry-standard equivalents but is specifically identified by the onsemi manufacturing origin and the DG package code indicating an 8-pin SOIC form factor suitable for surface-mount assembly.
