Overview
The LM2903PSRG4 is a dual differential voltage comparator manufactured by Texas Instruments, belonging to the LMx93/LM2903 series. It features two independent comparators with open-collector outputs designed for single-supply operation across a wide voltage range of 2V to 36V. The device supports a common-mode input voltage range that includes ground. Key electrical parameters include a maximum supply current of 1mA and an input offset voltage of up to 7mV. It operates within a temperature range of -40°C to +125°C and is housed in an 8-pin TSSOP package.
Feature Summary
- Dual differential voltage comparison capability with open-collector outputs
- Wide single-supply voltage operation from 2V to 36V
- Common-mode input voltage range includes ground potential
- Extended industrial operating temperature range up to 125°C
Applications
- Over-voltage and under-voltage monitoring circuits
- Window comparator configurations
- Level detection systems
- Temperature sensing interfaces
Procurement Notes
Verify the specific suffix 'SRG4' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging quantity and RoHS compliance status. Ensure the ordering part number matches the required package variant and environmental specifications before finalizing procurement orders.
Selection Notes
Select this component when a dual-channel comparator with open-collector outputs is required for single-supply applications. It is suitable for designs needing wide supply voltage tolerance and ground-referenced inputs. Consider the TSSOP-8 package constraints and thermal performance requirements for high-temperature environments.
Part Context
This device is part of the widely used LMx93/LM2903 family of dual comparators. It shares functional similarities with the LM293 and LM393 but offers specific package and environmental variations. The LM2903PSRG4 represents a lead-free, green (RoHS compliant) version in a shrink TSSOP package, facilitating surface-mount assembly.
Replacement Considerations
Compatible replacements include LM2903PWR, LM2903DR, and LM2903IDR. Verify pinout compatibility and electrical parameter limits such as supply voltage and temperature range before substituting.
