LM258AWYDT

Overview

The LM258AWYDT is a dual low-power operational amplifier manufactured by STMicroelectronics, featuring an SOIC-8 surface-mount package. It operates within a supply voltage range of 3 V to 30 V and supports a wide operating temperature range from -40 °C to +105 °C. Key electrical parameters include a gain-bandwidth product of 1.1 MHz, a slew rate of 600 mV/µs, and an input bias current of 20 nA. The device delivers an output current of 40 mA per channel with a typical input offset voltage of 1 mV.

Feature Summary

• Dual-channel architecture with internal frequency compensation for stable single-supply operation
• Rail-to-rail output capability allowing voltage swing down to ground potential
• Low power consumption with supply current independent of the supply voltage magnitude
• Wide common-mode input voltage range that includes the negative rail

Applications

• Transducer signal amplification
• DC gain block circuits
• Interface electronics for standard logic systems

Procurement Notes

Verify the specific suffix AWYDT against the manufacturer datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the SOIC-8 form factor. Confirm RoHS compliance status and moisture sensitivity level requirements for the assembly process before finalizing procurement orders.

Selection Notes

Select this component when a dual op-amp solution is required for single-supply applications with moderate bandwidth needs. The 1.1 MHz gain-bandwidth product suits general-purpose signal conditioning tasks. Consider the 40 mA output drive capability for direct interfacing with low-impedance loads without additional buffering stages.

Part Context

This part belongs to the LM258 family of low-power dual operational amplifiers designed for cost-effective single-supply implementations. The series is widely utilized in industrial and consumer electronics where power efficiency and simplified circuit design are prioritized over high-speed performance characteristics.
