BD7282YFJ-CE2

Overview

The BD7282YFJ-CE2 is a dual-channel, automotive-grade, high-speed CMOS operational amplifier featuring Nano Cap technology. It operates within a supply voltage range of 2.5 V to 5.5 V and supports an operating temperature from -40°C to +125°C. Key electrical parameters include a gain-bandwidth product of 7 MHz, a slew rate of 10 V/µs, and a typical input bias current of 500 fA. The device delivers a voltage gain of 115 dB, a common-mode rejection ratio of 100 dB, and an output current capability of 50 mA per channel. It exhibits low noise with an input voltage noise density of 12 nV/√Hz and a maximum input offset voltage of 10 µV.

Feature Summary

• Integrates Nano Cap technology to ensure stable operation without oscillation even when driving capacitive loads up to 1 nF.
• Provides rail-to-rail input and output capabilities for maximum dynamic range in single-supply applications.
• Features ultra-low input bias current and low noise characteristics suitable for precision signal conditioning.

Applications

• Engine control units
• Electric power steering systems
• Anti-lock braking systems
• Sensor amplifiers

Procurement Notes

Verify the specific suffix CE2 against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets AEC-Q100 automotive qualification requirements if intended for vehicle integration. Cross-reference the RoHS status and long-term availability plans directly with ROHM Semiconductor documentation prior to finalizing procurement decisions.

Selection Notes

Select this component for designs requiring high-speed performance combined with low noise in automotive environments. The dual-channel configuration reduces board space compared to single-channel alternatives. Verify that the 50 mA output current meets load requirements and that the 7 MHz bandwidth aligns with signal frequency needs. Consider the SOP-J8 package dimensions for PCB layout constraints.

Part Context

This part belongs to ROHM's Nano Cap series of automotive operational amplifiers. It is designed to replace older generation op-amps in modern vehicle electronics where stability under capacitive loading was previously a challenge. The series emphasizes reliability and precision for critical safety and control systems.

Replacement Considerations

Consult official substitution lists for equivalent dual-channel automotive op-amps with similar GBP and slew rate. Verify pin compatibility and thermal characteristics before replacing existing designs.
