Overview
The LM2903DG is a dual independent precision voltage comparator manufactured by onsemi, designed for single or split supply operation. It operates within a wide single-supply range of 2.0 Vdc to 36 Vdc and supports split supplies from ±1.0 Vdc to ±18 Vdc. The device features very low current drain of 0.4 mA, independent of supply voltage, and includes input ESD clamps. It utilizes an SOIC-8 package (D suffix) and functions across an operating ambient temperature range of -40 °C to +105 °C.
Feature Summary
- Dual independent precision voltage comparators capable of single or split supply operation
- Input common mode range extends to ground level during single supply operation
- Outputs compatible with DTL, ECL, TTL, MOS, and CMOS logic levels
- Integrated ESD clamps on inputs enhance device ruggedness
Applications
- Consumer electronics applications requiring precise voltage comparison
- Automotive electronic systems utilizing robust analog components
- Industrial electronics designs needing wide supply voltage flexibility
Procurement Notes
Verify the specific ordering suffix 'DG' corresponds to the SOIC-8 package and the -40 °C to +105 °C temperature grade as defined in the official onsemi documentation. Confirm RoHS compliance and Pb-Free status requirements against project specifications before procurement.
Selection Notes
Select this component when dual comparators are required within a single package to save board space. It is suitable for designs needing low power consumption independent of the supply voltage. Ensure the application does not require negative input voltages beyond the specified limits relative to ground.
Part Context
This part belongs to the LMx93 series family, which includes variants like LM393 and LM293. While sharing core architecture, the LM2903 variant specifically offers an extended industrial temperature range compared to commercial versions. The 'DG' suffix identifies the specific package type and thermal performance characteristics.
Replacement Considerations
LM2903DR2G: Tape and reel version of the same device. LM2903DMR2G: Micro8 package alternative. LM393DG: Commercial temperature grade equivalent.
