LM258PG4

Overview

The LM258PG4 is a dual operational amplifier manufactured by Texas Instruments, belonging to the LM258A series. It features a wide single-supply voltage range of 3 V to 32 V or dual supplies of ±1.5 V to ±16 V. The device provides a gain-bandwidth product of 700 kHz and a slew rate of 0.3 V/µs. Input characteristics include a maximum input offset voltage of 5 mV and an input bias current of 150 nA. Each channel can deliver up to 20 mA of output current with a common-mode rejection ratio of 70 dB. It operates within a temperature range of -55°C to +125°C and is housed in an 8-pin PDIP package.

Feature Summary

• Dual-channel general-purpose operational amplifier architecture
• Wide single or split power supply operation capability
• Rail-to-rail output swing functionality
• Extended industrial temperature range support

Applications

• General-purpose analog signal conditioning circuits
• Sensor interface amplification stages
• Active filter designs
• Voltage comparator applications

Procurement Notes

Verify the specific suffix PG4 indicates the lead-free PDIP-8 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ordering quantities align with standard packaging configurations provided by distributors. Cross-reference the exact part number against current Texas Instruments availability lists to confirm production status and lifecycle stage before finalizing procurement plans.

Selection Notes

Select this component for cost-sensitive designs requiring dual amplification channels in a through-hole format. The LM258PG4 offers sufficient bandwidth for low-frequency applications but lacks the high-speed performance required for RF or video processing. Consider the 20 mA output drive capability against load requirements. Evaluate the 700 kHz gain-bandwidth product against signal frequency needs to ensure adequate loop stability and gain accuracy in the target circuit topology.

Part Context

This device is part of the widely adopted LM258 family, serving as a legacy dual operational amplifier solution. The LM258PG4 specifically denotes the lead-free version packaged in an 8-pin Plastic Dual In-line Package (PDIP). It maintains pin compatibility with earlier non-green variants while adhering to modern environmental standards. The component is designed for robust performance in industrial and consumer electronics where reliable analog signal processing is essential.

Replacement Considerations

Direct pin-compatible replacements include the LM258DRG4 for surface-mount implementations and the LM258P for standard PDIP packages. Verify that substitute parts meet the same electrical specifications regarding offset voltage and supply voltage ranges. Ensure thermal performance and package dimensions are compatible with existing board layouts when transitioning between package types.
