LM158AH/NOPB

Overview

The LM158AH/NOPB is a military-grade dual operational amplifier from Texas Instruments. It features a gain-bandwidth product of 700 kHz and a slew rate of 300 mV/us. The input offset voltage is 2 mV, with an input bias current of 150 nA. Operating supply voltage ranges from 3 V to 32 V single supply or ±1.5 V to ±16 V dual supply. Quiescent current per channel is 500 uA. Output current capability is 20 mA per channel. Common-mode rejection ratio is 80 dB, and input voltage noise density is 40 nV/sqrt Hz. It utilizes a TO-99-8 package for through-hole mounting.

Feature Summary

• Military-grade construction designed for extreme temperature environments ranging from -55 C to +125 C
• Dual high-gain internal frequency compensation amplifiers suitable for wide voltage range operation
• Input common-mode voltage range includes ground, allowing direct sensing near zero volts

Applications

• Military electronic systems requiring high reliability
• Precision signal conditioning circuits in harsh environments
• Active filter designs operating under wide thermal cycling conditions

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free status and RoHS compliance requirements against current project specifications. Confirm the TO-99-8 ceramic package matches the target PCB footprint and thermal management strategy. Ensure the military rating aligns with environmental qualification standards for the intended deployment scenario.

Selection Notes

Select this component when military-grade reliability and extended temperature performance are mandatory. The 700 kHz bandwidth suits moderate-speed applications where low power consumption is prioritized over high-speed slew rates. Consider the TO-99-8 package constraints for automated assembly processes compared to standard plastic packages.

Part Context

This device belongs to the LM158 family of dual operational amplifiers. It shares architectural similarities with commercial variants but undergoes stricter testing protocols to meet military specifications. The NOPB designation signifies a non-plumb compliant version manufactured by Texas Instruments.

FAQ

Does the LM158AH/NOPB support rail-to-rail output?

No, the datasheet specifies output swing headroom to the positive supply is typically -2 V, indicating it does not reach the positive rail.

What is the maximum differential input voltage?

The differential input voltage range equals the maximum rated supply voltage, which is 32 V.
