LM258WYDT

Overview

The LM258WYDT is a low-power dual operational amplifier manufactured by STMicroelectronics, housed in an 8-SOIC surface-mount package. It features two independent, high-gain, internally frequency-compensated amplifiers designed for single power supply operation over a wide voltage range. Key electrical parameters include a gain-bandwidth product of 1.1 MHz, a slew rate of 0.6 V/µs, and a maximum input offset voltage of 5 mV. The device operates with a supply voltage span from 3 V to 30 V, drawing a typical supply current of 700 µA. It supports an output current of up to 60 mA per channel and functions within a temperature range of -40°C to 105°C.

Feature Summary

• Internally frequency compensated for stability without external components
• Single-supply operation capability including ground-referenced inputs and outputs
• Low power consumption largely independent of supply voltage magnitude
• Automotive grade qualification compliant with AEC-Q100 standards

Applications

• Transducer amplifiers
• DC gain blocks
• Interface electronics for logic systems
• General-purpose linear circuits

Procurement Notes

Verify the specific suffix WYDT against official STMicroelectronics documentation to confirm package type and automotive qualification status. Ensure compatibility with required operating temperatures and supply voltages. Cross-reference datasheet revisions to confirm pinout and electrical characteristics match design requirements before integration.

Selection Notes

Select this component for applications requiring low power dissipation and single-supply functionality. The internal frequency compensation simplifies circuit design by eliminating external compensation networks. Consider the 8-SOIC package dimensions for PCB layout constraints and verify thermal performance within the specified operating temperature range.
