LM258WDT

Overview

The LM258WDT is a dual operational amplifier manufactured by STMicroelectronics, housed in an 8-SOIC surface-mount package. It operates within a supply voltage range of 3 V to 30 V and supports a working temperature range from -40°C to +105°C. Key electrical specifications include a gain-bandwidth product of 1.1 MHz, a slew rate of 0.6 V/µs, and an input bias current of 20 nA. The device delivers a maximum output current of 60 mA per channel with a typical supply current of 700 µA. It features an input offset voltage of 2 mV and holds AEC-Q100 automotive qualification.

Feature Summary

• Dual-channel architecture providing two independent general-purpose amplifiers in a single compact package
• Automotive-grade reliability certified under the AEC-Q100 standard for harsh environment operation
• Low power consumption design suitable for battery-powered applications with minimal quiescent current draw
• Wide single-supply voltage capability allowing direct interfacing with various logic families

Applications

• Transducer signal conditioning circuits
• Active filter implementations
• Voltage comparators in control systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct package type and tape-and-reel specifications. Confirm that the AEC-Q100 automotive qualification status aligns with your project requirements. Check for any recent Product Change Notifications regarding moisture sensitivity levels or packaging materials before finalizing procurement orders.

Selection Notes

Select this component when a dual op-amp solution is required for space-constrained designs needing automotive reliability. The 8-SOIC package offers a balance between thermal performance and board space efficiency. Ensure the application does not require high-speed signaling exceeding the 1.1 MHz bandwidth limit or rail-to-rail output swing capabilities.

Part Context

This part belongs to the LM258 family of low-power dual operational amplifiers produced by STMicroelectronics. The 'W' designation indicates the SOIC package variant, while 'DT' specifies the tape and reel packaging format. This series is widely recognized for its cost-effectiveness and robust performance in general-purpose analog signal processing tasks across industrial and consumer electronics sectors.

Replacement Considerations

Cross-reference with other LM258 variants such as LM258D or LM258N for pin-compatible alternatives. Verify that substitute parts maintain the same AEC-Q100 qualification if automotive compliance is mandatory. Ensure replacement components match the 8-SOIC footprint and electrical characteristics defined in the original datasheet.
