Overview
The onsemi LM2903DR2G is a dual independent precision voltage comparator designed for single or split supply operation. It features a wide single-supply range of 2.0 Vdc to 36 Vdc and a split-supply range of ±1.0 Vdc to ±18 Vdc. The device offers very low current drain, typically 0.4 mA, which remains independent of the supply voltage. Input specifications include a low bias current of 25 nA and an input offset voltage of up to 7.0 mV. The output is compatible with DTL, ECL, TTL, MOS, and CMOS logic levels.
Feature Summary
- Capable of single or split supply operation with a wide voltage range
- Features very low current drain that is independent of supply voltage
- Includes input common mode range extending to ground level
- Output voltage is compatible with various logic families including TTL and CMOS
Applications
- Consumer electronics applications
- Automotive systems requiring unique site control
- Industrial electronics designs
Procurement Notes
Verify the specific suffix DR2G corresponds to the SOIC-8 tape and reel packaging configuration. Confirm the operating temperature range aligns with project requirements, as the LM2903 variant supports -40°C to +105°C. Ensure compliance with RoHS standards and Pb-Free package requirements during procurement validation.
Selection Notes
Select this component when dual comparators are needed within a single package to save board space. Consider the open-collector output structure for interfacing with different logic families. Evaluate the input offset voltage and bias current specifications against signal integrity requirements in precision sensing circuits.
Part Context
This part belongs to the LM393 series family, which includes variants like LM293, LM393, and NCV2903. These devices share similar architectural characteristics but differ in temperature ranges and automotive qualification status. The LM2903 specifically targets industrial and commercial environments with extended temperature capabilities compared to standard commercial grades.
Replacement Considerations
LM2903DG serves as a rail-pack alternative. LM2903EDR2G provides equivalent functionality in the same surface-mount package. Cross-reference with LM393DR2G for general-purpose replacements where temperature ratings may vary.
