Overview
The KA2903DMTF is a dual differential comparator manufactured by onsemi, housed in an 8-SOIC surface-mount package. It operates within a supply voltage range of 2V to 36V for single supplies or ±1V to ±18V for dual supplies. Key electrical specifications include a maximum input offset voltage of 7mV at 5V and a typical output current capability of 16mA at 5V. The device functions reliably across an extended temperature range from -40°C to +85°C.
Feature Summary
- Differential input architecture for precise signal comparison
- Wide single and dual power supply voltage compatibility
- High output drive current capability for direct load interfacing
Applications
- Voltage level detection circuits
- Threshold sensing applications
- Over-voltage protection systems
Procurement Notes
Verify the specific suffix 'MTF' against official datasheets to confirm tape-and-reel packaging details. Confirm RoHS compliance status through manufacturer documentation. Ensure the 8-SOIC footprint matches the target PCB design constraints before finalizing procurement decisions.
Selection Notes
Select this component when a dual comparator with wide supply range is required. Consider the 16mA output current for driving low-impedance loads without external buffering. Evaluate the 7mV offset voltage specification against system accuracy requirements for precision thresholding tasks.
Part Context
This part belongs to the KA2903 series of dual comparators from onsemi. It shares functional similarities with other industry-standard dual comparator devices but offers specific performance characteristics tailored for general-purpose analog signal processing and switching applications in consumer and industrial electronics.
Replacement Considerations
Publicly confirmed substitute part numbers include LM2903DR2G, LM2903VDR2G, LM393DR2G, and NCV2903DR2G from onsemi. Verify pinout compatibility and electrical parameter overlaps before substituting.
