LF411MWGRLQMLV

Overview

The LF411MWGRLQMLV is a low-offset, low-drift JFET input operational amplifier designed for space applications. It features internally trimmed offset voltage and ELDRS-free radiation tolerance up to 100 krad(Si). The device offers a gain bandwidth of 3 MHz, a slew rate of 10 V/µs, and low supply current of 1.8 mA. It operates within a temperature range of -55°C to 125°C and utilizes a Ceramic Flatpack (CFP) package.

Feature Summary

• ELDRS-free radiation hardness up to 100 krad(Si)
• Internally trimmed low input offset voltage
• Low input bias and offset currents
• High slew rate and wide gain bandwidth

Applications

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

Procurement Notes

Verify the specific ordering suffix and radiation qualification level against the latest datasheet before procurement. Confirm that the CFP package dimensions match your PCB footprint requirements. Ensure environmental testing protocols align with MIL-STD-883 standards for critical space missions.

Selection Notes

Select this component when low drift and high-speed performance are required in radiation-hardened environments. It serves as a direct pin-compatible upgrade for standard LM741 designs needing improved offset and drift characteristics. Consider the CFP package constraints for thermal management and board layout.

Part Context

This part belongs to the LF411QML series, which provides production data for military and aerospace specifications. It is manufactured by Texas Instruments under the SNOSAO6C document revision. The device is distinct from commercial variants due to its rigorous quality conformance inspection and radiation testing.

Replacement Considerations

The LF411QML is pin compatible with the standard LM741. Designers can upgrade existing LM741 designs to benefit from lower offset voltage and drift without changing the circuit layout.
