BA3404FVM-TR

Overview

The BA3404FVM-TR 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, supporting both single and dual power configurations. Key electrical characteristics include a gain-bandwidth product of 1.2 MHz, a slew rate of 1.2 V/µs, and an input bias current of 70 nA. The device features a maximum input offset voltage of 2 mV and delivers an output current of 30 mA per channel. It is housed in an MSOP-8 surface-mount package and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Ground sense capability allowing input and output signals to operate near the negative supply rail (VSS).
• Wide single-supply voltage operation ranging from 4 V to 36 V for flexible power integration.
• Differential input configuration with high common-mode rejection ratio.

Applications

• Sensor signal conditioning circuits requiring ground-referenced inputs.
• Industrial control systems utilizing wide-voltage single-supply architectures.
• Battery-powered equipment where low quiescent current and wide supply tolerance are required.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeiting risks. Confirm RoHS compliance status and specific tape-and-reel packaging specifications prior to order placement. Ensure that the MSOP-8 footprint matches your PCB design guidelines. Check for any end-of-life notifications or recommended replacement alternatives if planning long-term production runs.

Selection Notes

Select this component when designing circuits that require dual amplifiers with ground-sense functionality and wide supply voltage tolerance. It is suitable for applications needing moderate bandwidth and low input bias current without the complexity of external compensation. Consider the MSOP-8 package constraints regarding thermal dissipation and board space compared to larger packages.
