Overview
The LM2903DMR2G is a dual independent precision voltage comparator manufactured by onsemi. It supports single supply operation from 2.0 Vdc to 36 Vdc or split supplies of ±1.0 Vdc to ±18 Vdc. The device features an input common mode range extending to ground level and a differential input voltage range equal to the power supply voltage. Electrical characteristics include a maximum input offset voltage of 7.0 mV, typical input bias current of 20 nA, and large signal response time of 1.5 µs. It operates within a temperature range of -40°C to +105°C and is housed in a Micro8 package.

Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and shipping configuration. Ensure the component meets the required operating temperature range and electrical specifications for the intended application environment before finalizing procurement decisions.
Selection Notes
Select this component when dual comparators are required with low input offset voltage and ground-referenced input capability. Consider the Micro8 package constraints for board space and thermal management. Validate that the supply voltage range aligns with system requirements and that open-collector outputs suit the logic interface needs.
Part Context
This part belongs to the LMx93 series of dual comparators from onsemi, which includes variants like LM393, LM293, and LM2903. These devices share similar core functionalities but differ in temperature ranges and specific electrical parameters. The LM2903 variant specifically targets extended industrial temperature applications compared to commercial grade options.

FAQ
What is the input common mode voltage range?
The input common mode voltage range extends from ground level up to VCC minus 1.5 V.
Can the differential input voltage exceed the supply voltage?
Yes, the differential input voltage range is equal to the power supply voltage, and voltages larger than the supply do not damage the inputs.
