BA2902YF-CE2

Overview

The BA2902YF-CE2 is a quad operational amplifier manufactured by Rohm Semiconductor, designed for automotive applications. It features ground-sense input and output capabilities, allowing operation from VEE to VCC-1.5V. The device operates on a single supply voltage ranging from +3.0V to +36V or dual supplies of ±1.5V to ±18V. Key electrical specifications include a typical supply current of 0.7mA, an input bias current of 20nA, and an input offset voltage of 2mV at 25°C. It provides a large signal voltage gain of 100 V/mV, a slew rate of 0.2V/µs, and a gain-bandwidth product of 0.5MHz. The component supports an output source current of 30mA and functions within a temperature range of -40°C to +125°C.

Feature Summary

Ground-sense input and output capability allows direct sensing near the ground level.
Wide operating supply voltage range supports both single and dual power supply configurations.
Low supply current consumption suitable for power-sensitive automotive electronics.
High open-loop voltage gain ensures effective signal amplification.

Applications

Engine Control Units (ECU)
Electric Power Steering (EPS) systems
Anti-Lock Braking Systems (ABS)

Procurement Notes

Verify the specific package type and suffix against the manufacturer's datasheet before ordering. Confirm that the intended application environment falls within the specified operating temperature range and supply voltage limits. Ensure compliance with AEC-Q100 qualification requirements if used in automotive safety-critical circuits. Check for any functional safety support documentation relevant to the design.

Selection Notes

Select this component when ground-referenced signal processing is required in automotive environments. Consider the low supply current for battery-operated systems. Verify that the quad configuration meets the channel count needs compared to dual-channel alternatives. Ensure the SOP14 package fits the PCB layout constraints.

Part Context
