BA2902F-E2

Overview

The BA2902F-E2 is a quad operational amplifier manufactured by ROHM Semiconductor, housed in an SOP-14 surface-mount package. It operates on a single supply voltage ranging from 3 V to 36 V or dual supplies up to ±18 V. Key electrical parameters include a gain-bandwidth product of 500 kHz, a slew rate of 0.2 V/µs, and a maximum input offset voltage of 7 mV. The device draws a typical circuit current of 0.7 mA per channel and supports an output current of 30 mA. It functions within a temperature range of -40 °C to +125 °C.

Feature Summary

• Ground sense capability allowing input and output voltages to operate near the negative supply rail (GND).
• Wide operating supply voltage range supporting both single and dual power configurations.
• High large signal voltage gain for precise analog signal processing.

Applications

• General-purpose analog signal conditioning circuits.
• Sensor interface applications requiring ground-referenced inputs.
• Battery-powered systems utilizing wide voltage range operation.

Procurement Notes

Verify the specific suffix 'E2' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Confirm that the SOP-14 package dimensions match your PCB footprint requirements. Check for any recent lifecycle notices regarding this component, as older variants may have different availability or substitution recommendations.

Selection Notes

Select this component when ground-sense input/output functionality is required with a wide supply voltage range. It is suitable for general-purpose amplification where moderate speed (500 kHz GBW) is sufficient. Consider alternative packages if higher channel density or smaller footprint is needed, such as the LM2902 series in SSOP-B14.

Part Context

This part belongs to the BA2902 family of standard ground sense operational amplifiers. It is designed for cost-effective analog applications requiring low power consumption and robust performance across industrial temperature ranges. The E2 suffix typically denotes environmental compliance and specific manufacturing revisions.

Replacement Considerations

LM2902F-E2: Quad op-amp with similar ground sense features but slightly different electrical characteristics (0.8 MHz GBW, 0.3 V/µs slew rate). Verify pinout compatibility between SOP-14 variants before substitution.
