Overview
The LM2903IMX is a dual independent voltage comparator manufactured by onsemi, designed for single or split supply operation. It features an open-collector output type and operates within a supply voltage range of 2 V to 36 V. The device has a typical input offset voltage of 7 mV and an input bias current of 250 nA. It provides a maximum output current of 16 mA per channel with a response time of 1.5 µs. Operating at a quiescent current of 1 mA, it is housed in an 8-SOIC surface-mount package.
Feature Summary
- Dual independent precision voltage comparators capable of single or split supply operation
- Low offset voltage design for accurate signal comparison
- Open-collector outputs allow flexible interfacing with various logic families
Applications
- General-purpose voltage monitoring circuits
- Threshold detection systems
- Over-voltage protection circuits
Procurement Notes
Verify the specific suffix IMX corresponds to the SOIC-8 surface-mount package variant from onsemi. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering quantity aligns with standard reel sizes if applicable. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.
Selection Notes
Select this component when low offset voltage and wide supply range are required for dual-channel comparison tasks. The open-collector output necessitates external pull-up resistors for proper logic level translation. Consider the 1.5 µs response time for speed-sensitive applications. Verify thermal performance within the SOIC-8 package constraints for the intended power dissipation levels.
Part Context
The LM2903 series belongs to onsemi's family of low-power, low-offset voltage dual comparators. It shares functional similarities with the LM393 but offers optimized performance characteristics for precision applications. The device is part of a widely used industry-standard comparator lineup, ensuring broad availability and established design support across multiple electronic sectors.
