5962R2321401PXE

Overview

The Texas Instruments 5962R2321401PXE is a radiation-hardened, QML-P qualified quad operational amplifier. It features rail-to-rail input and output capabilities with a supply voltage range of ±20V to ±40V. The device operates within a frequency bandwidth of 4.5MHz and supports military temperature ranges from -55°C to +125°C. Packaged in a 14-pin TSOT-23 thin form factor, it utilizes gold wire bonding and NiPdAu lead finishes for enhanced reliability in harsh environments.

Feature Summary

• Radiation-hardened design ensuring reliability in high-radiation environments
• Quad configuration with rail-to-rail input and output operation
• Military-grade temperature range support from -55°C to +125°C
• QML-P qualification with single controlled baseline fabrication

Applications

• Spacecraft avionics systems
• Satellite communication payloads
• High-reliability military instrumentation
• Nuclear facility monitoring equipment

Procurement Notes

Verify the specific suffix PXE matches your required package and tape-and-reel specifications. Confirm radiation hardness assurance (RHA) documentation is included for mission compliance. Ensure the supplier provides traceability certificates consistent with QML-P standards. Check for any agency-specific approval requirements before finalizing procurement orders.

Selection Notes

Select this component when radiation tolerance and wide supply voltage are critical. The rail-to-rail feature maximizes dynamic range in low-voltage signal chains. Verify that the 14-pin TSOT-23 package fits your board layout constraints. Consider the 4.5MHz bandwidth against your signal processing requirements to ensure adequate performance margins.

Part Context

This part belongs to Texas Instruments' radiation-hardened analog signal chain portfolio. It is designed for aerospace and defense applications where standard commercial components would fail due to ionizing radiation effects. The QML-P qualification ensures strict manufacturing controls and testing protocols aligned with military specifications.

Replacement Considerations

Direct replacements must match the 5962R prefix for equivalent radiation hardness. Verify pinout compatibility with the 14-pin TSOT-23 package. Ensure substitute parts maintain the same ±20V to ±40V supply range and rail-to-rail characteristics. Cross-reference MIL-PRF-38535 Class Q or K qualifications if higher reliability tiers are needed.
