LM2903MX/ELLI958

Overview

The LM2903MX/ELLI958 is a dual differential comparator manufactured by Texas Instruments. It features an open-collector output type with rail-to-rail capability. The device operates within a supply voltage range of 2V to 30V for single supplies or ±1V to ±15V for dual supplies. It is housed in an 8-SOIC package and contains two independent comparison channels.

Feature Summary

• Dual differential comparison architecture
• Open-collector output configuration
• Rail-to-rail output swing capability

Applications

• Prototype circuit development
• Voltage level detection systems
• General-purpose analog signal comparison

Procurement Notes

Verify the specific suffix ELLI958 against official Texas Instruments documentation, as it may indicate a prototype or non-standard variant. Confirm RoHS compliance status and exact packaging details directly with the manufacturer or authorized distributors before procurement. Ensure the component matches the required 8-SOIC footprint and electrical specifications for the intended application.

Selection Notes

Select this component when a dual-channel comparator with open-collector outputs is required. The rail-to-rail feature allows for maximum dynamic range in low-voltage applications. Verify that the 2V to 30V supply range meets the system power constraints. Consider the 8-SOIC package size for PCB layout compatibility.

Part Context

This part belongs to the LM2903 family of dual comparators from Texas Instruments. The base model LM2903MX is a standard industrial-grade device. The ELLI958 suffix suggests a specific batch, prototype run, or distributor-specific designation rather than a functional variation of the core LM2903 architecture.

Replacement Considerations

Standard equivalents include LM2903MX/NOPB for commercial grade devices. For automotive applications, consider the LM2903BQDDFRQ1. Verify pinout compatibility and electrical parameters such as propagation delay and input offset voltage when substituting.
