Overview
The LM2903FVM-TR is a dual analog comparator from ROHM Semiconductor, housed in an MSOP-8 surface-mount package. It operates on a supply voltage range of 3V to 32V with a typical quiescent current of 600µA. The device features open-collector outputs capable of sourcing 16mA per channel and supports differential inputs. Key electrical parameters include a maximum input offset voltage of 4.5mV, a typical response time of 1µs, and an operating temperature range from -40°C to +125°C.
Feature Summary
- Ground-sense input and output capability allows operation near ground potential.
- Open-collector output structure facilitates flexible interfacing with various logic families.
- Wide operating supply voltage range supports diverse single-supply applications.
Applications
- General-purpose signal comparison circuits
- Voltage monitoring systems
- Threshold detection applications
Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official datasheets as required by project specifications. Ensure the MSOP-8 footprint matches the PCB layout design. Check for any end-of-life notifications or recommended new design warnings associated with this specific part number before finalizing procurement plans.
Selection Notes
Select this component when a dual comparator with low power consumption and wide voltage tolerance is required. The MSOP-8 package suits space-constrained designs. Verify that the 16mA output drive current meets load requirements. Consider the 4.5mV max offset voltage for precision needs. Ensure the -40°C to +125°C temperature range aligns with environmental conditions.
Part Context
This part belongs to the LM2903 series of general-purpose analog comparators manufactured by ROHM Semiconductor. It shares functional similarities with other industry-standard dual comparators but offers specific performance characteristics such as low offset voltage and wide supply range within the MSOP-8 form factor.
Replacement Considerations
LM2903DGKR is listed as a similar alternative. Verify pinout compatibility and electrical parameter alignment before substitution.
