Overview
The LM111WGRLQMLV is a radiation-hardened voltage comparator manufactured by Texas Instruments. It operates from a single 5V supply or dual supplies ranging from ±2.5V to ±15V. The device features a maximum input bias current of 100nA and an offset current of 20nA max. It provides high dose rate tolerance up to 50 krad(Si). The component is housed in a 10-lead Ceramic Flat Pack (CFP) package and functions within a temperature range of -55°C to 125°C.
Feature Summary
- Radiation hardened design ensuring reliability in high-radiation environments
- Ultra-low input bias current for high-impedance signal applications
- Operates from standard single or dual power supply configurations
Applications
- Military aerospace systems requiring radiation tolerance
- High-reliability industrial control circuits
- Precision voltage monitoring in harsh environments
Procurement Notes
Verify the specific ordering suffix to confirm radiation hardening status and ceramic packaging. Ensure compatibility with existing board layouts for the 10-CFP package. Confirm that the operating voltage ranges align with system requirements. Check for any specific handling instructions related to ceramic packages.
Selection Notes
Select this component when radiation hardness is mandatory for the application environment. Consider the low input bias current for interfacing with high-impedance sensors. Evaluate the thermal performance within the specified -55°C to 125°C range. Compare against non-radiation-hardened alternatives if environmental conditions permit.
Part Context
This part belongs to the LM111 family of voltage comparators, specifically the QML-qualified variants designed for extreme environments. The 'W' indicates ceramic construction, while 'GRLQMLV' denotes the specific radiation-hardened and lead-free compliant configuration offered by Texas Instruments for defense and space markets.
Replacement Considerations
Direct replacements must match the radiation hardness level and ceramic package type. Non-QML equivalents may lack the required 50 krad(Si) tolerance. Verify pinout compatibility before substituting with other LM111 variants.
