BA2904F-E2

Overview

The BA2904F-E2 is a dual-channel ground sense operational amplifier manufactured by Rohm Semiconductor. It operates within a supply voltage range of 3 V to 36 V and supports an operating temperature from -40 °C to +125 °C. Key electrical parameters include a typical circuit current of 0.7 mA, a gain-bandwidth product of 500 kHz, and a slew rate of 200 mV/µs. The device features a maximum input offset voltage of 2 mV, an input bias current of 20 nA, and can deliver up to 30 mA per channel output current.

Feature Summary

Supports ground-sense input and output capabilities for low-side signal processing
Operates with wide single-supply voltage ranges suitable for automotive and industrial environments
Provides high output drive capability for direct interfacing with loads

Applications

Current sensing applications in automotive systems
Industrial control circuits requiring ground-referenced signals
Consumer electronics utilizing single-supply operation

Procurement Notes

Verify the component status as Not Recommended for New Designs (NRND) before integration into new products. Confirm package details correspond to SOP-8 specifications. Ensure compliance with RoHS directives and check for specific environmental certifications required by the target application market. Validate that existing inventory meets long-term supply requirements due to potential phase-out schedules.

Selection Notes

Select this component when ground-sense input functionality is required alongside moderate bandwidth and high output drive. Compare against LM2904 variants if pin compatibility or specific noise characteristics differ. Consider the BA2902FV-E2 for quad-channel configurations. Verify thermal performance within the specified -40 °C to +125 °C range for harsh environment deployments.

Part Context

This part belongs to the BA2904 series of standard ground sense operational amplifiers produced by Rohm Semiconductor. It shares architectural similarities with the LM2904 family but offers specific optimizations for ground-referenced operations. The device is designed for robust performance in automotive and industrial sectors where wide supply voltage tolerance is critical.
