BA2904WFV-E2

Overview

The BA2904WFV-E2 is a dual-channel ground sense operational amplifier manufactured by ROHM Semiconductor. It operates on a single power supply ranging from +3.0V to +36.0V and supports an extended temperature range of -40°C to +125°C. Key electrical specifications include a maximum input offset voltage of 2mV, a typical supply current of 0.5mA, and a gain-bandwidth product of 0.5MHz. The device features a slew rate of 0.2V/µs and provides an output source current of up to 30mA. It is housed in an SSOP-B8 package.

Feature Summary

Operates with a single power supply within a wide voltage range
Input and output stages support ground sensing capability
Features low input offset voltage for precision applications
Designed for high reliability across an extended industrial temperature range

Applications

Current sense circuits
Buffer amplifiers
Active filter designs
Consumer electronics systems

Procurement Notes

Verify the component status as Not Recommended for New Designs (NRND) before initiating procurement. Confirm that the SSOP-B8 package variant matches the specific footprint requirements of the target PCB layout. Ensure compatibility with existing design constraints given the end-of-life recommendation for new implementations.

Selection Notes

Select this component when a dual-channel op-amp with ground-sense capability is required for single-supply operation. The low input offset voltage makes it suitable for precision signal conditioning tasks. Consider the thermal dissipation limits at higher ambient temperatures if operating near the maximum supply voltage or load current ratings.

Part Context

This part belongs to the BA2904 series of general-purpose operational amplifiers produced by ROHM Semiconductor. The series integrates two independent op-amps on a single silicon monolithic integrated circuit chip. The 'W' suffix indicates the specific low offset voltage variant, while 'FV' denotes the SSOP-B8 package type.
