JM38510/11402BGA

The JM38510/11402BGA is a military-grade single JFET-input operational amplifier manufactured by Texas Instruments, supplied in a hermetic TO-99 metal can package. As a JAN (Joint Army-Navy) qualified device designated by the JM38510 prefix, this amplifier is processed and screened in accordance with MIL-PRF-38510, ensuring stable operation over the full military temperature range, typically −55°C to +125°C. The JFET input stage delivers ultra-low input bias currents, often in the picoampere region, along with high input impedance and low offset voltage drift, which minimizes signal loading and maintains precision in high-impedance sensor interfaces. The TO-99 package provides a hermetically sealed cavity, offering strong resistance to moisture and atmospheric contaminants in demanding environments.

These amplifiers are widely used in aerospace and defense electronics, including avionics computers, radar signal conditioning, guidance and navigation subsystems, and secure communications hardware. Industrial applications include precision integrators, sample-and-hold stages, photodetector amplifiers, and other data acquisition front-ends where low leakage and high common-mode rejection are critical. Military-qualified components such as the JM38510/11402BGA are typically sourced through authorized distribution with full lot traceability and may require mandatory documentation, including certificates of conformance and test reports. Lead times can be extended due to specialized screening flows, and procurement teams should evaluate long-term availability, as hermetic metal can ICs are subject to obsolescence pressure as suppliers transition to surface-mount packaging. Export compliance under ITAR or EAR regulations may also apply.
