LM258DRE4

Overview

The LM258DRE4 is a dual operational amplifier manufactured by Texas Instruments, featuring an industry-standard architecture. It operates within a supply voltage range of 3 V to 32 V or ±1.5 V to ±16 V. Key electrical parameters include a gain-bandwidth product of 700 kHz and a slew rate of 0.3 V/µs. The device provides a typical input offset voltage of 3 mV and an input bias current of 20 nA. It supports a maximum output current of 40 mA per channel and delivers a common-mode rejection ratio of 80 dB. The component functions across a temperature range of -25°C to 85°C and utilizes an 8-SOIC surface-mount package.

Feature Summary

• Dual-channel general-purpose operational amplifier design
• Single-supply operation capability from 3 V to 32 V
• Rail-to-rail output functionality for extended dynamic range
• Low power consumption suitable for battery-powered applications

Applications

• Transducer amplifiers
• Active filters
• DC gain blocks

Procurement Notes

Verify the specific suffix 'E4' indicates lead-free construction compliant with RoHS standards. Confirm the 'DR' designation corresponds to the SOIC-8 tape and reel packaging format. Ensure the operating temperature grade matches the industrial specification of -25°C to 85°C for the intended environment. Cross-reference the manufacturer part number with distributor codes to prevent ordering errors due to similar family members.

Selection Notes

Select this component when a low-cost, dual-channel solution is required for single-supply systems. The rail-to-rail output allows signal swings close to the supply rails, maximizing dynamic range in low-voltage designs. Compare input offset voltage and bias current specifications against application requirements to ensure adequate precision. Consider the 40 mA output drive capability for direct interfacing with moderate loads without additional buffering stages.

Part Context

This device belongs to the LM258 family of dual operational amplifiers, which are widely recognized as industry standards. It shares functional similarities with the LM358 but offers improved performance characteristics such as lower input offset voltage and higher bandwidth. The family is designed for versatile analog signal processing tasks, providing a balance between cost-effectiveness and reliable performance in consumer and industrial electronics.
