BA2904WF-E2

Overview

The BA2904WF-E2 is a dual-channel ground sense operational amplifier manufactured by ROHM Semiconductor. It operates on a single supply voltage ranging from 3V to 36V 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 provides a slew rate of 0.2V/µs and can deliver up to 30mA output source current. It is housed in an SOP-8 surface-mount package.

Feature Summary

• Operates with a single power supply within a wide voltage range
• Input and output stages are capable of ground sensing
• 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 specific ordering suffix against official documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status through the manufacturer's datasheet or certification documents before procurement. Ensure the component meets the required operating temperature range for the intended application environment.

Selection Notes

Select this component when a dual-channel amplifier requires ground-sense capability and operation at supply voltages up to 36V. The low input offset voltage makes it suitable for precision signal conditioning tasks. Verify that the SOP-8 package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the BA2904 series of general-purpose operational amplifiers. The 'W' designation indicates a variant optimized for lower input offset voltage compared to standard versions. The '-E2' suffix typically denotes embossed tape and reel packaging for automated assembly processes.
