BA2902YFV-CE2

Overview

The BA2902YFV-CE2 is a standard ground-sense operational amplifier manufactured by Rohm Semiconductor. It features four independent circuits housed in a 14-pin SSOP-B14 surface-mount package. The device operates within a supply voltage range of 3 V to 36 V and supports dual supplies from 1.5 V to 18 V. Key electrical specifications include a gain-bandwidth product of 500 kHz, a slew rate of 200 mV/µs, and an input bias current of 20 nA. It delivers a channel output current of 30 mA with a quiescent supply current of 700 µA. The component is qualified under AEC-Q100 standards for automotive applications and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Ground-sense capability allowing input voltage ranges extending down to the negative supply rail (VEE).
• Automotive-grade qualification compliant with AEC-Q100 reliability standards.
• Low power consumption suitable for battery-operated systems with a typical supply current of 700 µA.

Applications

• Automotive sensor signal conditioning
• Battery management system monitoring
• Industrial control circuit interfaces

Procurement Notes

Verify the specific suffix CE2 against the official Rohm datasheet to confirm pinout and electrical tolerances. Confirm the AEC-Q100 qualification status if automotive compliance is required. Check the lifecycle status as this part may be designated as Not Recommended for New Designs (NRND). Ensure the SSOP-B14 package dimensions match the target PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a quad operational amplifier requires ground-referenced input signals without needing negative supply rails. The 500 kHz bandwidth and 30 mA output current support moderate-speed general-purpose applications. Consider the 14-pin SSOP-B14 package constraints for board space. Verify that the 3 V minimum supply voltage aligns with the system's lowest operating condition.

Part Context

This device belongs to the BA2902 series of ground-sense operational amplifiers designed for robust performance in demanding environments. The BA2902YFV-CE2 variant specifically utilizes the SSOP-B14 package format. It serves as a specialized solution for applications requiring single-supply operation with inputs capable of reaching the negative rail, distinguishing it from standard op-amps that require headroom above the negative supply.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative quad op-amps based on pinout and ground-sense specifications.
