Overview
The LM111H/NOPB is a single-channel general-purpose analog voltage comparator manufactured by Texas Instruments. It features an open-collector output and operates within a supply voltage range of 5 V to 36 V. The device draws a typical operating current of 6 mA and provides a maximum channel output current of 50 mA. Key electrical specifications include a response time of 200 ns, an input offset voltage (Vos) of 3 mV, and an input bias current (Ib) of 100 nA. It utilizes differential inputs and supports a power dissipation of 500 mW. The component is housed in an 8-pin TO-99 metal can package and is rated for operation between -55°C and +125°C.
Feature Summary
- Provides high-speed voltage comparison with a 200 ns response time for precise signal detection.
- Features an open-collector output capable of sourcing up to 50 mA for flexible interfacing.
- Operates on a wide single or dual power supply ranging from 5 V to 36 V.
- Ensures stable performance across extreme temperatures from -55°C to +125°C.
Applications
- Precision threshold detection circuits
- Over-voltage protection systems
- Window comparator designs
Procurement Notes
Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS status as per the manufacturer's datasheet. Confirm the package type is the 8-pin TO-99 metal can variant. Ensure the ordering part number matches the exact functional requirements for the general-purpose comparator application.
Selection Notes
Select this component when a robust, high-output-current comparator is required for industrial environments. The TO-99 package offers superior thermal and mechanical stability compared to plastic packages. Consider the 3 mV offset voltage for applications requiring moderate precision without external trimming.
Part Context
This device belongs to the LM111 series of analog comparators from Texas Instruments. It serves as a military-grade or high-reliability alternative to standard plastic-packaged comparators. The series is designed for applications demanding long-term stability and resistance to harsh environmental conditions.
Replacement Considerations
The LT1011CH is documented as a similar replacement option, though it is marked as obsolete. Verify pin compatibility and electrical parameter alignment before substitution.
