Procurement Notes

This specific part number represents a military-grade variant often subject to restricted distribution channels. Verification of the official manufacturer datasheet is essential to confirm current availability status and lead times, as supply may be limited or produced to order. Ensure all procurement requests align with the authorized distributor network to guarantee authenticity and traceability.

Selection Notes

Select this component when designing systems that demand strict military reliability standards combined with high-speed analog performance. The JFET input makes it suitable for high-impedance sources where low bias current is critical. Compare against commercial grade alternatives only if environmental constraints allow, noting that the military version offers broader temperature tolerance and stricter parameter controls.

Part Context

This part belongs to the broader LM101 series of operational amplifiers, which are classic high-performance devices. The '5962' prefix indicates it is a direct-from-fabrication military part number assigned by the Defense Logistics Agency. It serves as a specialized, high-reliability version of standard commercial op-amps, tailored for long-term stability and radiation hardness in critical infrastructure.

Replacement Considerations

Direct replacements must match the military qualification and CDIP-8 package. Verify pin compatibility with other LM101 variants such as LM101AH or LM101AJ, but ensure the replacement also meets the specific QPA suffix requirements for temperature and testing standards. Cross-reference with official TI substitution guides for approved equivalents.

FAQ

What is the input bias current characteristic of this JFET-input op amp?

The JFET input stage provides a very low input bias current, significantly lower than bipolar counterparts, making it ideal for high-impedance signal sources.

Is this component suitable for high-frequency applications?

Yes, the device features a high slew rate, allowing it to handle fast-changing signals effectively, though bandwidth should be verified against specific application requirements.
