Overview
The LM2903FVT-E2 is a dual analog comparator manufactured by ROHM Semiconductor, housed in an 8-pin TSSOP surface-mount package. It operates on a single power supply ranging from 3V to 32V or dual supplies of ±1.5V to ±16V. The device features two independent circuits with open-collector outputs capable of sinking up to 16mA. Key electrical characteristics include a maximum input offset voltage of 4.5mV at 1.4V and a typical input bias current of 50nA. It supports ground-sensed inputs and outputs, functioning within an operating temperature range of -40°C to +125°C.
Feature Summary
- Ground-sensed input and output capability allowing operation near the negative rail
- Wide operating supply voltage range supporting both single and dual power configurations
- Open collector output structure enabling flexible logic interface compatibility
Applications
- General purpose analog signal comparison
- Voltage monitoring circuits
- Threshold detection systems
Procurement Notes
Verify the specific suffix E2 confirms RoHS compliance and lead-free status as per manufacturer documentation. Confirm the TSSOP-B8 package dimensions match the design footprint requirements. Ensure the operating temperature grade meets the environmental constraints of the target application. Cross-reference the datasheet revision to ensure all electrical parameters align with current production standards.
Selection Notes
Select this component when a dual comparator with ground-referenced input/output is required for wide-voltage applications. The low input bias current and moderate offset voltage make it suitable for general-purpose sensing where high precision is not critical. Consider the thermal performance and package size relative to available board space and heat dissipation needs.
Part Context
This part belongs to the LM2903 series of dual comparators from ROHM Semiconductor. It is designed as a standard-grade industrial component intended for general electronic equipment. The series is characterized by its ability to operate with low power consumption while maintaining functionality across a broad voltage spectrum, distinguishing it from higher-speed or automotive-specific variants.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source material.
