BA3404F-E2

Overview

The BA3404F-E2 is a dual-channel ground sense operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 4 V to 36 V single supply or ±2 V to ±18 V dual supply. Key electrical parameters include a gain-bandwidth product of 1.2 MHz, a slew rate of 1.2 V/µs, and an input offset voltage of 2 mV. The device features low input bias current of 70 nA and delivers up to 30 mA output current per channel. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Ground sense input capability allowing operation near the negative supply rail
• Wide single-supply voltage operation supporting high-voltage applications
• Integrated phase compensation for stable performance without external components

Applications

• Industrial sensor signal conditioning
• High-voltage analog processing circuits
• Battery management system monitoring

Procurement Notes

Verify component authenticity through authorized distributors as the part status is listed as obsolete. Confirm package integrity and pin alignment against the SOP-8 specification sheet before integration. Ensure design compliance with the specified thermal and electrical limits to maintain reliability in final assemblies.

Selection Notes

Select this component when wide supply voltage tolerance and ground-referenced input are required. Compare specifications against newer alternatives if long-term availability is critical. Evaluate the trade-off between the 1.2 MHz bandwidth and power consumption for specific application constraints.

Part Context

This device belongs to the BA3404 series of operational amplifiers designed for robust analog signal processing. It utilizes CMOS technology to achieve low power consumption while maintaining high voltage handling capabilities. The series is characterized by its ability to interface directly with ground-level signals in single-supply systems.

Replacement Considerations
