LM258DG4

Overview

The LM258DG4 is a dual operational amplifier manufactured by Texas Instruments, housed in an 8-pin Small Outline Integrated Circuit (SOIC) package. It features a voltage-feedback architecture with internal frequency compensation. Key electrical specifications include a maximum average bias current of 0.1 µA at 25°C and a nominal common-mode rejection ratio of 80 dB. The device has a maximum input offset voltage of 4000 µV. It operates within a standard temperature range and complies with RoHS standards.

Feature Summary

• Dual operational amplifier configuration with integrated frequency compensation for stability
• Voltage-feedback architecture designed for general-purpose signal processing applications

Applications

• General-purpose analog signal conditioning circuits
• Sensor interface amplification stages
• Active filter implementations

Procurement Notes

Verify the specific datasheet revision and manufacturing date code upon procurement to ensure compliance with current environmental regulations. Confirm that the SOIC-8 package dimensions match the target PCB footprint requirements. Check for any recent product change notices regarding material composition or testing standards before finalizing component selection for production.

Selection Notes

Select this component when a dual-channel solution is required with low bias current characteristics. The internal frequency compensation simplifies circuit design by eliminating external components typically needed for stability. Ensure the application does not require rail-to-rail output swing, as this device utilizes a standard output stage architecture suitable for single-supply operations.

Part Context

This part belongs to the LM258 family of dual operational amplifiers produced by Texas Instruments. It shares functional similarities with other variants in the series but is distinguished by its specific SOIC-8 surface-mount packaging. The 'G4' suffix indicates lead-free construction and compliance with specific environmental directives defined by the manufacturer.
