JL411BPA

Overview

The JL411BPA is a military-grade, low offset, low drift JFET input operational amplifier manufactured by Texas Instruments. It features internally trimmed offset voltage and ensured input offset voltage drift for high precision applications. The device utilizes Bi-FET II technology to provide very low input bias and offset currents alongside high input impedance. It operates within a supply voltage range of ±4V to ±26V and supports an operating temperature range from -55°C to +125°C. Key electrical characteristics include a minimum slew rate of 7 V/µs, a typical gain bandwidth of 3 MHz, and a maximum power dissipation of 400 mW.

Feature Summary

• Internally trimmed offset voltage with ensured drift specifications
• Low input bias current and low input noise current density
• High slew rate and wide gain bandwidth product
• High input impedance utilizing large reverse breakdown voltage JFET devices

Applications

• High speed integrators
• Fast D/A converters
• Sample and hold circuits

Procurement Notes

Verify the specific ordering suffix (e.g., JM38510/11904BPA) against the Package Option Addendum to confirm lead finish and environmental classification. Confirm that the component status is LIFEBUY or ACTIVE as required for your design lifecycle. Ensure the package type matches the NAB0008A drawing for the 8-lead ceramic dual-in-line configuration.

Selection Notes

Select this component when designing systems requiring guaranteed low offset voltage drift over a wide industrial or military temperature range. The internal trimming eliminates the need for external offset nulling circuitry in many configurations. Consider the 400 mW power dissipation limit and thermal resistance values when determining heat sinking requirements for dense packaging.

Part Context

The JL411BPA belongs to the LF411 family of precision amplifiers but is distinguished by its military qualification under MIL-STD-883 standards. Unlike commercial variants, it undergoes rigorous Group A quality conformance inspections including dynamic and functional tests at extreme temperatures. This ensures reliability in harsh environments where standard commercial parts may fail.
