LM258ADRG4

Overview

The LM258ADRG4 is a dual operational amplifier manufactured by Texas Instruments, belonging to the LM258A series. It features a voltage-feedback architecture housed in an 8-pin SOIC package with tape-and-reel packaging. Key electrical parameters include a gain-bandwidth product of 700 kHz and a slew rate of 300 mV/µs. The device operates within a supply voltage range of 3 V to 32 V (single) or ±1.5 V to ±16 V (dual). Input characteristics specify a maximum input offset voltage of 3 mV and an input bias current of 80 nA at 25°C. Each channel provides an output current capability of 20 mA, with a typical power supply current of 350 µA.

Feature Summary

• Dual operational amplifier configuration with rail-to-rail output capability
• Low power consumption suitable for battery-operated applications
• Internal frequency compensation ensures stability without external components

Applications

• Transducer amplifiers for signal conditioning
• Active filters in audio and instrumentation circuits
• General-purpose analog signal processing

Procurement Notes

Verify the specific suffix 'DG4' indicates lead-free composition and RoHS compliance as per Texas Instruments standards. Confirm the 'R' designation corresponds to tape-and-reel packaging for automated assembly. Ensure the 'A' grade specification matches design requirements for tighter offset voltage tolerances compared to standard LM258 variants. Cross-reference the manufacturer part number against official TI databases to validate authenticity and current production status.

Selection Notes

Select this component when low power dissipation and single-supply operation are required. The LM258ADRG4 offers improved offset voltage specifications over the standard LM258. Consider the SOIC-8 package for surface-mount designs. Verify that the 700 kHz bandwidth meets the application's frequency response needs. Ensure the 20 mA output drive is sufficient for the connected load impedance.
