Overview
The LM2903PWR is a dual differential voltage comparator manufactured by Texas Instruments, belonging to the LMx93/LM2903 series. It features open-collector outputs and operates from a single power supply ranging from 2 V to 36 V. The device supports a common-mode input voltage range that includes ground. Key electrical parameters include a typical response time of 1.3 µs, a maximum supply current of 2.5 mA, and an output sink current capability of 6 mA per channel. It is housed in an 8-pin TSSOP package and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Dual differential voltage comparison with open-collector outputs for flexible interfacing
- Wide single-supply voltage operation from 2 V to 36 V
- Common-mode input voltage range extends to ground potential
- Designed for rapid switching applications with low propagation delay
Applications
- Overvoltage and undervoltage monitoring circuits
- Window comparator designs
- Threshold detection systems
- Level shifting interfaces
Procurement Notes
Verify the specific suffix 'PWR' corresponds to the TSSOP-8 package and tape-and-reel packaging configuration. Confirm RoHS compliance status and ensure the operating temperature range meets the application's environmental requirements. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when dual independent comparators are required in a compact surface-mount package. It is suitable for designs needing wide supply voltage flexibility and ground-referenced inputs. Consider the open-collector output structure for compatibility with various logic families or pull-up resistor configurations.
Part Context
The LM2903PWR is part of the industry-standard LMx93 family, which includes variants like the LM193, LM293, and LM393. These devices are widely used as general-purpose analog comparators. The 'PWR' designation specifically indicates the plastic small-outline thin-shrink package (TSSOP) variant produced by Texas Instruments.
Replacement Considerations
