LM158YDT

Overview

The LM158YDT is an automotive-grade, low-power dual operational amplifier manufactured by STMicroelectronics. It features two independent, high-gain, internally frequency-compensated amplifiers designed for single power supply operation over a wide voltage range of 3 V to 30 V. The device provides a large DC voltage gain of 100 dB and a unity-gain bandwidth of 1.1 MHz. It includes a low input bias current of 20 nA and operates within a temperature range of -55°C to +125°C. Packaged in an SO-8 surface-mount format, it meets AEC-Q100 standards.

Feature Summary

• Automotive grade qualification compliant with AEC-Q100 standards
• Internally frequency compensated for stability without external components
• Input common-mode voltage range includes the negative rail (ground)
• Low power supply drain essentially independent of supply voltage magnitude

Applications

• Transducer amplifiers
• DC gain blocks
• Single power supply logic system interface electronics

Procurement Notes

Verify that the specific order code matches the required automotive grade specifications and package type. Confirm the tape and reel packaging configuration aligns with automated assembly requirements. Ensure the component meets the necessary environmental compliance standards for the intended deployment environment.

Selection Notes

Select this component when designing circuits requiring robust performance across extreme temperature variations typical of automotive environments. It is suitable for applications needing direct interfacing with standard 5 V logic systems without additional power supplies. Consider its internal frequency compensation for simplified circuit design.

Part Context
