BD87522YFJ-CE2

Overview

The BD87522YFJ-CE2 is a dual-channel CMOS operational amplifier designed for automotive applications, featuring EMARMOUR technology for high EMI immunity. It operates within a supply voltage range of 4 V to 15 V and supports rail-to-rail input and output. Key electrical parameters include a gain-bandwidth product of 2.3 MHz, a slew rate of 2.4 V/µs, and an input offset voltage of 100 µV. The device draws 3.95 mA of operating current per channel and provides an output drive capability of 9.3 mA. It functions reliably across a temperature range of -40°C to +125°C and is housed in an SOP-8 package.

Feature Summary

• EMARMOUR technology provides excellent electromagnetic interference immunity for robust automotive performance.
• Rail-to-rail input and output capabilities maximize dynamic signal range in single-supply systems.
• High output drive strength supports direct connection to low-impedance loads such as sensors and actuators.

Applications

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

Procurement Notes

Verify the specific suffix CE2 against the manufacturer's official datasheet to confirm pinout compatibility and packaging specifications. Ensure the component meets AEC-Q100 automotive qualification requirements for your target application environment. Cross-reference the RoHS status with current regulatory standards before finalizing procurement decisions.

Selection Notes

Select this component when high EMI resistance is critical alongside moderate bandwidth requirements. The rail-to-rail I/O feature makes it suitable for low-voltage single-supply designs where signal swing maximization is necessary. Consider the 2.3 MHz gain-bandwidth product for applications requiring faster response than standard general-purpose amplifiers but not demanding ultra-high-speed performance.

Part Context

This part belongs to ROHM's EMARMOUR series of automotive operational amplifiers. These devices are engineered to withstand harsh electromagnetic environments typical in modern vehicles. The dual-channel configuration allows for cost-effective implementation of differential signals or dual independent channels in compact SOP-8 packages.

Replacement Considerations

Check for functional equivalents with similar EMI immunity ratings and rail-to-rail capabilities. Verify that any substitute matches the 4 V to 15 V supply range and SOP-8 footprint. Ensure the replacement maintains comparable output drive current and gain-bandwidth specifications for circuit compatibility.
