BD87521G-LBTR

Overview

The BD87521G-LBTR is a single-channel CMOS operational amplifier from ROHM Semiconductor, featuring EMARMOUR technology for enhanced electromagnetic interference immunity. It supports a wide supply voltage range of 4V to 15V and offers rail-to-rail input and output capabilities. Key electrical specifications include a gain-bandwidth product of 2.3 MHz, a slew rate of 2.4 V/µs, and an input offset voltage maximum of 100 µV. The device operates with a typical quiescent current of 1.98 mA per channel and provides an output current capability up to 16.5 mA.

Feature Summary

• EMARMOUR technology provides superior electromagnetic interference (EMI) immunity
• Rail-to-rail input and output operation across the full supply range
• High output drive capability suitable for demanding load conditions

Applications

• Sensor signal amplification in industrial equipment
• Battery-powered devices requiring low power consumption
• Industrial control systems with high EMI environments

Procurement Notes

Verify the specific suffix LBTR against the official datasheet to confirm package type and tape-and-reel configuration. Ensure the operating temperature range meets system requirements, as industrial variants may differ from standard versions. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and avoid counterfeit components.

Selection Notes

Select this component when high EMI resistance is critical alongside rail-to-rail performance. The wide supply voltage range allows flexibility in single-supply designs. Compare the 2.3 MHz bandwidth against application signal frequencies to ensure adequate speed without unnecessary power consumption. Consider the SSOP-5 package constraints for PCB layout density.

Part Context

This component belongs to ROHM's EMARMOUR series, designed specifically for robustness in noisy environments. It complements other precision amplifiers by offering improved noise immunity without sacrificing drive capability. The series targets industrial applications where traditional op-amps might fail due to electromagnetic disturbances.

Replacement Considerations

Direct substitutes require matching EMARMOUR features and rail-to-rail I/O. Verify pin compatibility and electrical parameters such as GBW and supply voltage range before substitution.
