LM258ADT

Overview

The LM258ADT is a dual low-power operational amplifier manufactured by STMicroelectronics, housed in an 8-SOIC surface-mount package. It features a gain-bandwidth product of 1.1 MHz and a slew rate of 0.6 V/µs. The device operates within a supply voltage range of 3 V to 30 V (single) or ±1.5 V to ±15 V (dual). Key electrical specifications include a maximum input offset voltage of 3 mV, input bias current of 50 nA, and output current capability of 40 mA per channel. It supports an operating temperature range from -40°C to +105°C and holds AEC-Q100 automotive qualification.

Feature Summary

• Internally frequency compensated for stability without external components
• Single-supply operation with common-mode voltage including ground
• Output voltage swings to ground potential
• Low power consumption independent of supply voltage magnitude

Applications

• Transducer amplifiers
• DC gain blocks
• Interface electronics for logic systems
• Conventional op amp circuits in single supply systems

Procurement Notes

Verify the specific suffix 'DT' corresponds to the SOIC-8 tape-and-reel packaging configuration. Confirm AEC-Q100 automotive grade status if required for the application. Check RoHS compliance documentation for environmental regulations. Ensure the supplier provides the official STMicroelectronics datasheet for the LM258A series to validate the 3 mV offset voltage specification typical for the AD variant.

Selection Notes

Select this component when a dual operational amplifier with low power drain and single-supply compatibility is required. The LM258ADT offers improved offset voltage performance compared to standard LM258 variants. Consider the 8-SOIC package for surface-mount assembly constraints. Verify that the 1.1 MHz bandwidth and 40 mA output current meet the signal processing and load driving requirements of the target circuit design.

Part Context

This part belongs to the LM258A family of dual operational amplifiers. It shares functional similarities with the LM158 and LM358 but offers tighter electrical tolerances. The device is designed for general-purpose analog signal conditioning tasks where low power consumption and wide supply voltage flexibility are critical design parameters.

Replacement Considerations

LM258AMDREP is listed as a substitute part number.
