BD87522YFVM-CTR

Overview

The BD87522YFVM-CTR is a dual-channel CMOS operational amplifier from ROHM Semiconductor, designed for automotive applications. It features rail-to-rail input and output capabilities with a wide operating voltage range of 4V to 15V. Key electrical parameters include a typical gain-bandwidth product of 2.3 MHz, a slew rate of 2.4 V/µs, and an input offset voltage maximum of 1 mV. The device draws approximately 1.975 mA per channel and offers high output drive capability with a typical output current of 16.5 mA. It operates within a temperature range of -40°C to 125°C and is housed in an MSOP-8 package.

Feature Summary

• EMARMOUR™ technology provides superior electromagnetic interference immunity, reducing design burden by minimizing the need for external noise suppression components.
• Rail-to-rail input and output operation allows for maximum dynamic range utilization across the full supply voltage spectrum.
• High output drive capability supports direct connection to various loads without additional buffering stages.
• AEC-Q100 Grade 1 qualification ensures reliability and compliance with stringent automotive environmental standards.

Applications

• Sensor signal amplification in automotive systems
• Engine control unit (ECU) circuitry
• Electric power steering (EPS) controllers
• Anti-lock braking system (ABS) modules

Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging and tape configuration. Confirm that the specific revision matches the required AEC-Q100 Grade 1 qualification level for your automotive application. Check for any recent Product Change Notices (PCN) that may affect mechanical dimensions or documentation, although electrical characteristics typically remain unchanged. Ensure compatibility with your PCB footprint for the MSOP-8 package.

Selection Notes

Select this component when high EMI immunity is critical for maintaining signal integrity in noisy automotive environments. The rail-to-rail I/O characteristic makes it suitable for low-voltage single-supply designs where maximizing output swing is necessary. Consider the 2.3 MHz bandwidth and 2.4 V/µs slew rate for moderate-speed signal processing tasks. The dual-channel configuration in an MSOP-8 package offers space efficiency compared to single-channel alternatives.

Part Context

This device belongs to ROHM's EMARMOUR™ series of operational amplifiers, specifically engineered to address the increasing electromagnetic noise challenges in modern vehicles. The series integrates advanced circuit design, layout techniques, and process technologies to achieve exceptional noise tolerance. This particular model represents a dual-channel variant optimized for general-purpose automotive analog signal conditioning tasks requiring robust performance under harsh electrical conditions.

Replacement Considerations

Direct pin-compatible replacements within the same family include the BD87521YFVM-CTR (single channel) and BD87582YFVM-CTR (dual channel, similar specs). Verify that substitute parts maintain the same AEC-Q100 Grade 1 qualification and EMARMOUR™ EMI immunity levels. Ensure the replacement maintains the rail-to-rail input/output specification and comparable bandwidth and slew rate requirements for your specific application.
