BA2904YF-MGE2

Overview

The BA2904YF-MGE2 is a dual-channel automotive-grade operational amplifier manufactured by ROHM Semiconductor. It features a gain-bandwidth product of 0.5 MHz and a slew rate of 0.2 V/µs. The device operates on a single supply voltage ranging from 3.0V to 32V, or dual supplies of ±1.5V to ±16V. Key electrical specifications include a maximum input offset voltage of 7mV, typical input bias current of 20nA, and output current capability of 30mA. It provides high common-mode rejection ratio (CMRR) of 80dB and power supply rejection ratio (PSRR) of 100dB. The component is housed in an SOP-8 package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Supports ground-sense operation with input voltage range extending to the negative supply rail (VEE).
• Designed for automotive applications with AEC-Q100 qualification and functional safety support.
• Operates efficiently with low quiescent current consumption suitable for battery-powered systems.

Applications

• Automotive sensor signal conditioning circuits
• Current sensing applications requiring ground-referenced inputs
• Battery management system monitoring

Procurement Notes

Verify the specific suffix MGE2 against official ROHM documentation to confirm package dimensions and tape-and-reel specifications. Confirm that the NRND status does not impact existing production schedules. Ensure compatibility with automotive functional safety requirements if used in safety-critical loops. Cross-reference pin assignments with standard SOIC-8 layouts to prevent PCB integration errors during replacement.

Selection Notes

Select this component when ground-sense capability is required within a single-supply automotive environment. Compare CMRR and PSRR values against noise immunity requirements for the specific application. Verify that the 30mA output current meets load driving needs without external buffering. Consider the SOP-8 footprint constraints during layout design relative to thermal dissipation capabilities.

Part Context

This part belongs to the BA2904 series of dual operational amplifiers optimized for automotive use. It shares architectural similarities with other ROHM automotive op-amps but is distinguished by its specific ground-sense input stage and AEC-Q100 certification. The MGE2 suffix denotes the SOP-8 surface-mount packaging variant intended for automated assembly processes.

Replacement Considerations

LM2904EYFJ-CE2 is listed as a manufacturer-recommended alternative for related BA290x series components. Verify pinout compatibility and electrical parameter overlaps before substitution.
