LM258DRG3

Overview

The LM258DRG3 is a dual operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. 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 features a maximum input offset voltage of 5 mV and an input bias current of 20 nA. Each channel can deliver up to 40 mA of output current with a quiescent current of approximately 500 µA for both channels combined.

Feature Summary

• Dual-channel architecture providing two independent high-gain amplifiers in a single package
• Single-supply operation capability allowing direct interfacing with digital logic systems
• Internal frequency compensation ensures stability without external components
• Rail-to-rail output swing facilitates maximum dynamic range utilization

Applications

• Transducer signal conditioning circuits
• Active filter implementations
• DC gain blocks in measurement systems

Procurement Notes

Verify the specific suffix 'G3' against the official Texas Instruments datasheet to confirm it denotes the standard RoHS-compliant lead-free variant. Ensure the ordering part number matches the exact package style and temperature rating required for the design. Confirm availability status as manufacturing transitions may affect stock levels.

Selection Notes

Select this component when a general-purpose dual amplifier is needed for low-frequency applications requiring single-supply operation. It serves as a cost-effective alternative to precision amplifiers where moderate offset voltage and bandwidth are acceptable. Consider thermal dissipation requirements for the SOIC-8 package under continuous load conditions.

Part Context

This device belongs to the industry-standard LM258 family of dual operational amplifiers. It shares functional similarities with the LM358 and LM158, differing primarily in temperature range specifications. The LM258 series is widely recognized for its versatility in consumer electronics and industrial control applications.
