Overview
The JL111BGA is a voltage comparator manufactured by Texas Instruments, available in an active production status. It utilizes a TO-99 (LMC) metal can package with 8 pins and operates within a temperature range of -55°C to 125°C. The device supports single supply voltages from 5V up to ±15V, accommodating total supply voltages up to 36V. It features low input currents, differential input voltage ranges of ±30V, and offset voltage null capability. The output stage provides strobe functionality and allows for wire OR connections.
Feature Summary
- Features offset voltage null capability for precision balancing
- Includes strobe functionality to isolate inputs and outputs from system ground
- Supports wire OR'ing of outputs for flexible logic interfacing
Applications
- Digital transmission isolators
- Zero crossing detectors driving MOS logic
- Precision squarer circuits
Procurement Notes
Verify the specific military or aerospace qualification suffixes required for your application, as the JL111BGA designation indicates specialized variants under the LM111 family. Confirm that the TO-99 hermetic packaging meets your environmental requirements. Ensure proper handling procedures are followed due to limited built-in ESD protection on the leads.
Selection Notes
Select this component when high-speed comparison is needed alongside low power consumption and robust operating voltage ranges. Consider the TO-99 package if hermetic sealing is necessary for harsh environments. Evaluate the need for offset adjustment and strobing capabilities before finalizing the design, as these features require specific pin connections.
Part Context
The JL111BGA belongs to the LM111 family of voltage comparators produced by Texas Instruments. This family is designed to operate over a wide range of supply voltages, bridging standard op amp supplies down to single IC logic supplies. The JL111BGA specifically denotes a variant within this lineage, maintaining the core performance characteristics while adhering to specific packaging and qualification standards.
Replacement Considerations
The LM111JAN serves as a confirmed substitute part number within the same product family.
