LM111-MDE

Overview

The LM111-MDE is a voltage comparator manufactured by Texas Instruments, supplied as a bare die. It features an open-collector output and supports a maximum supply voltage of 36V with a minimum operating voltage of 5V. The device exhibits a maximum input offset voltage of 3mV and an input bias current of 100nA. It operates within a temperature range of -55°C to 125°C and includes strobe functionality.

Feature Summary

• Open-collector output configuration
• Strobe input capability
• Input offset voltage adjustment pin

Applications

• High-speed switching circuits
• Zero-crossing detectors
• Window comparators

Procurement Notes

Verify the specific die revision and pad configuration against the official datasheet before integration. Confirm that the substrate connection and thermal management requirements align with the target application's power dissipation limits. Ensure proper handling procedures for bare die components are established during assembly.

Selection Notes

Select this component when a high-speed comparator with low offset voltage is required in a form factor suitable for custom hybrid or monolithic integrated circuit designs. Consider the open-collector output requirement for external pull-up resistor implementation. Evaluate the thermal performance of the die package for the intended operating environment.

Part Context

This part belongs to the LM111 family of voltage comparators from Texas Instruments. The 'MDE' suffix indicates a military-grade specification and a bare die format, distinguishing it from standard packaged versions like DIP or TO-99. It shares functional similarities with other LM111 variants but offers specific reliability ratings for harsh environments.

Replacement Considerations

Direct substitutes include other LM111 variants such as LM111N or LM111J if packaging differences are acceptable. Verify electrical parameters and temperature ranges match the original design requirements.
