Overview
The LM2903PS-MAND is a dual differential voltage comparator manufactured by Texas Instruments, designed for single-supply operation. It features an SOIC-8 surface-mount package and includes two independent comparators within one device. The component supports a wide supply voltage range from 2 V to 36 V, with a typical operating supply current of 200 uA. It offers a response time of 1.3 us and can source up to 6 mA per channel output. The input offset voltage is typically 7 mV, and the input bias current is 25 nA. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Dual differential voltage comparison capability in a compact surface-mount package
- Wide single-supply voltage operation supporting low to high voltage systems
- Open-collector outputs allowing flexible interfacing with various logic families
- Industrial temperature range suitability for demanding environmental conditions
Applications
- Over-voltage and under-voltage detection circuits
- Window comparator applications for monitoring signal levels
- Interface between analog sensors and digital logic inputs
- Simple threshold detection in power management systems
Procurement Notes
Verify the specific suffix 'MAND' against official Texas Instruments documentation to confirm it denotes a standard commercial grade part without special automotive or military qualifications. Ensure the ordering information matches the exact SOIC-8 package type and pinout configuration required for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.
Selection Notes
Select this component when a dual comparator solution is needed for general-purpose threshold detection in industrial environments. Consider its wide supply voltage range and open-collector outputs for compatibility with diverse logic levels. Evaluate the 1.3 us response time against your application's speed requirements. Compare power consumption and package size against alternatives if space or energy efficiency are critical constraints.
Part Context
The LM2903PS-MAND belongs to the broader LM2903 family of dual differential comparators from Texas Instruments. This family shares similar core functionalities but varies in packaging, temperature ranges, and specific electrical characteristics. The PS variant indicates a plastic small-outline integrated circuit package, distinguishing it from through-hole or other surface-mount options like DR or M/NOPB.
Replacement Considerations
Potential substitutes include LM2903DR, LM2903M/NOPB, and LM2903P. Verify pin compatibility, supply voltage limits, and temperature ranges before substitution. The LM2903DR offers similar performance in a SOIC-8 reel package. The LM2903M/NOPB provides comparable specs in a tube-packaged SOIC-8. Always consult official datasheets to ensure functional equivalence.
