LM158DR

Overview

The LM158DR is a dual operational amplifier manufactured by UMW, featuring two independent, high-gain, internally frequency-compensated circuits. Designed for single power supply operation over a wide voltage range, it offers low-power supply drain independent of the supply voltage magnitude. The device supports input common-mode voltages including ground and allows output swing to ground. Key electrical characteristics include a large DC voltage gain of 100 dB, a unity-gain bandwidth of 1.1 MHz, and a low input bias current of 20 nA.

Feature Summary

• Internally frequency compensated for stability in standard op-amp configurations
• Capable of direct operation from standard 5 V logic system supplies
• Input common-mode voltage range includes the negative rail (ground)
• Output voltage swings to ground even with single-supply operation

Applications

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

Procurement Notes

Verify that the specific UMW part number matches the required package type and temperature grade. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring dual amplification with single-supply compatibility. It is suitable for applications where internal frequency compensation simplifies circuit design and eliminates external components typically needed for stability.

Part Context

This component belongs to the LM158 family of dual operational amplifiers. It shares functional similarities with industry-standard devices like the LM358 and LM258, providing a cost-effective solution for general-purpose analog signal processing tasks in consumer and industrial electronics.

Replacement Considerations

Cross-reference with LM358 or LM258 variants for pin-compatible replacements. Ensure substitute parts meet the same gain-bandwidth product and supply voltage requirements.
