LM258DR2G

Overview

The LM258DR2G is a dual operational amplifier from onsemi, housed in an SOIC-8 package. It operates with single supply voltages ranging from 3.0 V to 32 V or split supplies of ±1.5 V to ±16 V. Key electrical characteristics include a typical input offset voltage of 2.0 mV and an input bias current of 45 nA at 25°C. The device features internally compensated amplifiers with short-circuit protected outputs. It supports continuous output short circuits to ground and handles differential input voltages up to ±32 V. The operating temperature range extends from -25°C to +85°C.

Feature Summary

• True differential input stage allows common mode voltage range to extend to the negative supply rail.
• Outputs are short circuit protected against continuous shorts to ground.
• Internally compensated for stability without external components.
• Input ESD clamps enhance device ruggedness.

Applications

• Transducer amplifiers
• DC gain blocks
• Integrators

Procurement Notes

Verify the specific suffix DR2G corresponds to the SOIC-8 tape and reel packaging configuration. Confirm RoHS compliance status as indicated by the G suffix. Ensure the ordering code matches the required operating temperature range of -25°C to +85°C for the LM258 variant rather than the commercial LM358 grade.

Selection Notes

Select this component for applications requiring low power consumption and operation from a single supply down to 3.0 V. The wide common mode input range including ground simplifies biasing in single-supply designs. Consider the LM358 if a higher commercial temperature range is sufficient, or the NCV2904 for automotive qualification requirements.

Part Context

This part belongs to the LM258/LM358 family of single supply dual operational amplifiers. It utilizes circuit designs perfected for quad operational amplifiers, offering advantages over standard types like the MC1741 in single supply applications due to lower quiescent currents and extended input/output ranges.
