LM258DR

Overview

The LM258DR is a dual operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It features a gain-bandwidth product of 700 kHz and a slew rate of 300 mV/us. The device operates within a supply voltage range of 3 V to 32 V or ±1.5 V to ±16 V. Key electrical specifications include an input offset voltage of 3 mV, an input bias current of 80 nA, and a common-mode rejection ratio of 80 dB. Each channel provides an output current capability of 20 mA with a quiescent current of 350 uA. The component supports rail-to-rail input operation and functions across a temperature range of -25°C to +85°C.

Feature Summary

• Dual-channel general-purpose operational amplifier architecture
• Rail-to-rail input signal processing capability
• Wide single or split power supply voltage compatibility
• Surface-mount SOIC-8 packaging for automated assembly

Applications

• General-purpose analog signal conditioning circuits
• Transducer interface amplification stages
• Buffer and isolation applications in sensor networks
• Active filter implementations requiring low power consumption

Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to confirm pinout and electrical tolerances. Ensure the procurement source provides valid RoHS compliance certificates as required for modern electronic assemblies. Cross-reference the datasheet revision history to validate performance parameters against your design requirements before finalizing orders.

Selection Notes

Select this component when a dual op-amp solution is required with wide supply voltage flexibility and standard general-purpose performance characteristics. The SOIC-8 package facilitates compact PCB layout compared to through-hole alternatives. Consider the 700 kHz bandwidth limit for high-frequency signal integrity needs and verify that the 20 mA output drive meets load requirements without external buffering.

Part Context

This device belongs to the LM258 family of dual operational amplifiers produced by Texas Instruments. It serves as a surface-mount variant designed for cost-effective mass production in consumer and industrial electronics. The component shares functional similarities with other industry-standard dual op-amps but offers specific TI manufacturing tolerances and thermal characteristics defined in its official datasheet.

Replacement Considerations

LM258DRG4 is a verified equivalent part number from Texas Instruments representing the same functional device with updated environmental compliance markings.
