LM258WPT

Overview

The LM258WPT is a dual low-power operational amplifier manufactured by STMicroelectronics. It features two independent high-gain amplifiers with internal frequency compensation, designed for single-supply operation ranging from 3 V to 30 V. Key electrical parameters include a gain-bandwidth product of 1.1 MHz and a slew rate of 600 mV/μs. The device operates with a supply current of 700 μA per channel and provides an output current capability of 40 mA. Input characteristics specify a maximum input offset voltage of 5 mV and an input bias current of 150 nA. It supports surface-mount installation in a reel package format.

Feature Summary

• Internal frequency compensation ensures stability without external components
• Single-supply operation compatible with standard logic voltages
• Input common-mode voltage range includes ground potential
• Output voltage swing extends down to ground level

Applications

• Transducer signal amplification
• DC gain blocks in instrumentation
• Interface electronics for logic systems
• General-purpose linear circuits

Procurement Notes

Verify the specific suffix 'WPT' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and quantity. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the ordering code with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring low power consumption with single-supply compatibility. The 1.1 MHz bandwidth suits applications where moderate speed is sufficient. Verify that the 40 mA output drive capability meets load requirements. Consider the SOIC-8 or similar surface-mount package constraints during PCB layout planning.

Part Context

This part belongs to the LM258W series of dual operational amplifiers. It shares functional similarities with the LM158W and LM358W but offers specific performance characteristics tailored for low-power applications. The series is engineered to operate efficiently across a wide voltage range while maintaining stable performance under varying temperature conditions.

Replacement Considerations

Compatible substitutes include LM358 variants and LM158 equivalents. Verify pinout compatibility and electrical parameter alignment, particularly regarding supply voltage limits and output current capabilities, before implementing any cross-brand replacements.
