BA2902FV-E2

Overview

The BA2902FV-E2 is a quad ground sense operational amplifier manufactured by ROHM Semiconductor. It features four independent channels within an SSOP-14 surface-mount package. The device operates on a single power supply ranging from 3 V to 36 V, with a typical quiescent current of 700 uA per channel. Key electrical specifications include a gain-bandwidth product of 500 kHz, a slew rate of 200 mV/us, and an input offset voltage of 2 mV. Each channel provides an output current capability of 30 mA, while the common-mode rejection ratio is specified at 50 dB.

Feature Summary

• Supports ground sense input and output operation for signals near the negative rail
• Operates effectively with a wide single-supply voltage range
• Integrates internal phase compensation capacitors for stability

Applications

• General-purpose analog signal processing circuits
• Sensor interface applications requiring ground-referenced inputs
• Battery-powered systems utilizing single-supply configurations

Procurement Notes

Verify component status carefully as this part may be classified as Not Recommended for New Designs (NRND) or End-of-Life by the manufacturer. Confirm availability through authorized distributors and ensure that the specific SSOP-14 package variant matches the required PCB footprint. Cross-reference datasheet revisions to confirm pinout compatibility before finalizing procurement plans.

Selection Notes

Select this component when a quad amplifier configuration is required with ground-sense capabilities and low power consumption. It serves as a suitable alternative to standard op-amps in single-supply environments where input and output voltages must approach zero volts. Consider the 500 kHz bandwidth and 30 mA output drive when designing for moderate-speed signal conditioning tasks.

Part Context

This component belongs to the BA2902 series of standard ground sense operational amplifiers produced by ROHM Semiconductor. The series is designed for general-purpose applications requiring multiple amplifier channels in a compact surface-mount form factor. The BA2902FV-E2 specifically denotes the quad-channel version housed in an SSOP-14 package, distinguishing it from dual-channel variants like the BA2904.
