Overview
The LM2903DMR2G is a dual independent precision voltage comparator manufactured by onsemi, housed in an 8-lead Micro8 (MSOP) surface-mount package. It supports single supply operation from 2.0 Vdc to 36 Vdc and split supplies of ±1.0 Vdc to ±18 Vdc. The device features low input offset voltage, low input bias current, and open-collector outputs compatible with various logic families. Operating temperature range extends from -40°C to +105°C.
Feature Summary
- Dual independent precision comparators capable of single or split supply operation
- Input common mode range extends to ground level for single supply applications
- Open-collector output provides compatibility with DTL, ECL, TTL, MOS, and CMOS logic levels
- ESD clamps integrated on inputs to increase device ruggedness
Applications
- Consumer electronics requiring precise voltage monitoring
- Automotive electronic systems
- Industrial control and sensing circuits
Procurement Notes
Verify the specific ordering suffix 'DMR2G' corresponds to the Micro8 package and tape-and-reel shipping configuration. Confirm that the component meets RoHS compliance standards and lead-free requirements as specified in the manufacturer's documentation before finalizing procurement specifications.
Selection Notes
Select this component when dual comparators are required within a compact surface-mount footprint. Ensure the application operates within the specified -40°C to +105°C temperature range. Verify that the open-collector output interface aligns with the downstream circuit pull-up requirements and logic voltage levels.
Part Context
This part belongs to the LM2903 series of low offset voltage dual comparators produced by onsemi. It shares functional characteristics with the LM393 and LM293 series but offers extended industrial temperature ratings compared to commercial variants. The Micro8 package provides a space-efficient solution for modern PCB layouts.
