BD87582YFVM-CTR

Overview

The BD87582YFVM-CTR is a dual-channel CMOS operational amplifier from ROHM's EMARMOUR series, designed for automotive applications. It features rail-to-rail input and output capabilities with a wide operating supply voltage range of 4V to 14V. Key electrical specifications include a typical gain-bandwidth product of 4 MHz, a slew rate of 3.5 V/µs, and an input bias current of 0.001 nA. The device offers high common-mode rejection (60 dB) and power supply rejection (80 dB). It is AEC-Q100 Grade 1 qualified and housed in an 8-MSOP package.

Feature Summary

• EMARMOUR technology provides superior electromagnetic interference immunity, reducing the need for external noise suppression components.
• Rail-to-rail input and output operation allows for maximum dynamic range within the supply voltage limits.
• Automotive-grade reliability with AEC-Q100 Grade 1 qualification ensures durability in harsh environments.
• Low supply current consumption supports energy-efficient system designs.

Applications

• Sensor signal amplification in automotive systems
• Engine control unit (ECU) circuits
• Electric Power Steering (EPS) controllers
• Anti-lock Braking System (ABS) modules

Procurement Notes

Verify the specific suffix 'CTR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the component meets the functional safety support category requirements for your specific application design. Ensure compatibility with the 8-MSOP footprint dimensions during PCB layout verification.

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 applications where maximizing output swing is necessary. Consider the 4 MHz bandwidth for applications requiring moderate speed without excessive power consumption.

Part Context

This part belongs to the BD8758x series of EMARMOUR operational amplifiers, which are specifically engineered to address EMI challenges in electric vehicles and hybrid electric vehicles. The series includes variants with different channel counts and package options, all sharing the core high-immunity architecture developed through optimized circuit design and layout techniques.

Replacement Considerations

Direct pin-compatible replacements within the same family include BD87584YFVM-C for quad-channel applications. For single-channel needs, consider BD87521YG-CTR. Verify that alternative devices maintain comparable EMI performance levels if replacing with non-EMARMOUR parts.
