BD7285FV-LBE2

Overview

The BD7285FV-LBE2 is a Nano Cap™, low noise rail-to-rail input/output high-speed CMOS operational amplifier manufactured by ROHM Semiconductor. It integrates four independent channels in an SSOP-B16 package. Key electrical parameters include a gain-bandwidth product of 7 MHz, a slew rate of 10 V/µs, and a voltage gain of 115 dB. The device operates on a supply voltage range of 2.5 V to 5.5 V with a typical circuit current of 1.7 mA per channel. It features an equivalent input noise voltage density of 12 nV/√Hz, an input offset voltage maximum of 2 mV, and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates Nano Cap™ technology to ensure stability even when connected to output capacitors in the nanofarad range without oscillation.
• Provides rail-to-rail input and output capabilities for extended dynamic range operation.
• Designed as a long-term support product specifically for industrial equipment applications.

Applications

• Battery-powered devices requiring stable amplification
• Sensor signal conditioning circuits
• Industrial control systems

Procurement Notes

Verify the specific suffix LBE2 against the manufacturer's official datasheet to confirm packaging and tape-and-reel specifications. Ensure the order quantity aligns with the standard factory packing quantity of 2500 units. Confirm that the SSOP-B16 package dimensions match the target PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when four-channel amplification is required within a compact SSOP-B16 footprint. It is suitable for designs needing rail-to-rail performance and stability under capacitive loads. Consider the 125°C maximum operating temperature limit for high-temperature industrial environments. Verify that the 7 MHz bandwidth meets the signal processing speed requirements of the application.

Part Context

This part belongs to the BD728x series of high-speed CMOS operational amplifiers. It shares core architectural features with other members like the BD7282FJ-LB and BD7284F-LB, including the Nano Cap™ stabilization technology and low-noise characteristics. The primary distinction lies in the channel count and physical package type, offering a quad-channel configuration in an SSOP-B16 form factor compared to dual or single-channel alternatives.

Replacement Considerations

Check for direct pin-compatible substitutes within the BD728x family, such as the BD7284F-LB, ensuring the package and channel count match the design requirements. Verify that any alternative maintains the same Nano Cap™ stability and electrical performance metrics.
