BA2903FVM-TR

Overview

The BA2903FVM-TR is a dual analog comparator manufactured by ROHM Semiconductor, housed in an 8-MSOP surface-mount package. It operates on a single supply voltage ranging from 2 V to 36 V or dual supplies of ±1 V to ±18 V. The device features open-collector outputs capable of sourcing 16 mA per channel. Key electrical parameters include a typical response time of 1.3 µs, a maximum input offset voltage of 7 mV, and a typical input bias current of 5 nA. Quiescent current consumption is approximately 600 µA. The component supports a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Supports wide single-supply operation from 2.0 V to 36.0 V and dual-supply operation from ±1.0 V to ±18.0 V.
• Features standard comparator terminal connections allowing inputs and outputs to operate near ground potential.
• Includes built-in electrostatic protection circuits with a typical Human Body Model rating of ±5000 V.
• Utilizes gold pad construction for enhanced reliability.

Applications

• General-purpose signal comparison in industrial control systems
• Voltage monitoring circuits requiring low power consumption
• Threshold detection applications in consumer electronics

Procurement Notes

Verify the NRND (Not Recommended for New Designs) status before integration into new products. Confirm that the MSOP-8 package dimensions align with existing PCB footprints. Ensure supply chain stability as this component may be phased out in favor of newer alternatives. Check RoHS compliance documentation for specific regional regulatory requirements.

Selection Notes

Select this component when a dual-channel comparator with wide voltage tolerance and ground-sensing capability is required. Consider the 1.3 µs response time for speed-sensitive applications. Evaluate the 16 mA output drive capability against load requirements. Compare input offset voltage specifications if high precision is necessary for the target application.
