LM2903ITL/NOPB

Overview

The LM2903ITL/NOPB is a dual differential voltage comparator from Texas Instruments, housed in an 8-lead DSBGA package. It operates on a single supply voltage ranging from 2 V to 36 V. Key electrical parameters include a maximum input offset voltage of 7 mV and an input bias current of 250 nA. The device features a typical response time of 700 ns and draws a supply current of 500 uA. It supports rail-to-rail output swing and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual differential input configuration for precise signal comparison
• Rail-to-rail output capability for flexible interfacing
• Low power consumption with reduced supply current
• Compact surface-mount packaging for space-constrained designs

Applications

• General purpose analog signal processing
• Threshold detection circuits
• Low voltage monitoring systems

Procurement Notes

Verify the specific suffix NOPB indicates lead-free compliance and RoHS adherence. Confirm the DSBGA-8 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check for any automotive or industrial grade distinctions if applicable to your final assembly standards.

Selection Notes

Select this component when low power and small form factor are critical. The rail-to-rail output simplifies logic interface design compared to open-collector variants. Consider the 700 ns propagation delay for timing-sensitive applications. Verify that the 2 V minimum supply voltage aligns with your system's power rails.

Part Context

This part belongs to the LM2903-N series, which focuses on low power and low offset voltage performance. It serves as a modern alternative to traditional through-hole comparators, offering improved integration density. The DSBGA package provides thermal efficiency and board space savings compared to larger SOIC or DIP packages.

Replacement Considerations

Direct pin-compatible replacements may include other LM2903 variants with different packages such as LM2903DR or LM2903PWRG4. Verify package compatibility and electrical parameter tolerances before substitution.
