Overview
The LM2903MX/NAK1 is a dual differential voltage comparator from Texas Instruments, part of the LM193/LM293/LM393/LM2903 family. It operates on a single supply voltage ranging from 2V to 30V or dual supplies of ±1V to ±15V. The device features an open-collector output stage and is designed for low power consumption with a maximum quiescent current of 1mA. It supports rail-to-rail operation and is housed in an 8-SOIC package with a width of 0.154 inches (3.90mm).
Feature Summary
- Dual differential input voltage comparison capability
- Open-collector output stage design
- Low power consumption characteristics
- Rail-to-rail operational functionality
Applications
- General purpose voltage monitoring
- Threshold detection circuits
- Power supply supervision
Procurement Notes
Verify the specific suffix NAK1 against official Texas Instruments documentation to confirm it denotes a prototype or specific tape-and-reel configuration distinct from standard NOPB variants. Ensure the ordering information matches the exact package dimensions and RoHS compliance status listed in the manufacturer's datasheet before finalizing procurement.
Selection Notes
Select this component when a dual comparator with low offset voltage and single-supply operation is required. Consider the open-collector output requirement for pull-up resistor implementation. Verify that the 8-SOIC package fits the PCB layout constraints and that the operating voltage range aligns with the system power rails.
Part Context
This device belongs to the widely used LMx93/LM2903 series of dual comparators. These components are industry-standard replacements for older LM193 and LM293 designs, offering improved performance while maintaining pin compatibility. The MX suffix indicates a tape-and-reel packaging format suitable for automated assembly processes.
Replacement Considerations
LM2903MX/NOPB is a verified equivalent variant within the same family. Other compatible parts include LM2903D, LM2903MDA, and LM2903MEP, provided the package type and electrical specifications match the application requirements.
