BD7284F-LBE2

Overview

The BD7284F-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 on a single chip, featuring a gain-bandwidth product of 7 MHz and a slew rate of 10 V/µs. The device operates within a supply voltage range of 2.5 V to 5.5 V with a typical circuit current of 1.7 mA per channel. Key electrical specifications include an equivalent input noise voltage density of 12 nV/√Hz, an input offset voltage of 1.6 mV, and a voltage gain of 115 dB. It supports an operating temperature range from -40°C to +125°C and is housed in a SOP-J14 package.

Feature Summary

• Integrates Nano Cap™ technology to ensure stability even when driving output capacitors up to 1 nF without oscillation.
• Provides rail-to-rail input and output capabilities for maximum dynamic range in low-voltage applications.
• Delivers low input-referred noise voltage density suitable for precision sensor signal conditioning.
• Designed for long-term support in industrial equipment markets.

Applications

• Battery-powered portable devices requiring low power consumption and high precision.
• Sensor amplifier circuits where low noise and high slew rate are critical.
• Industrial control systems requiring stable operation with capacitive loads.

Procurement Notes

Verify the specific suffix LBE2 against the manufacturer's latest datasheet to confirm packaging details and tape-and-reel specifications. Ensure compatibility with SOP-J14 footprint requirements during PCB layout. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the part number with official ROHM distributors to validate availability and authenticity before procurement.

Selection Notes

Select this component when designing circuits that require four-channel amplification with rail-to-rail performance in a compact SOP-J14 package. It is suitable for applications demanding low noise and high speed under single or dual supply voltages between 2.5 V and 5.5 V. Consider its Nano Cap™ feature if the design involves significant output capacitance to avoid stability issues. Evaluate the 1.7 mA/ch current consumption against battery life requirements for portable systems.

Part Context

This part belongs to the BD7284F-LB series of high-speed CMOS operational amplifiers. It is part of ROHM's Nano Cap™ family, which emphasizes stability with capacitive loads. The device is positioned as a long-term support product for industrial applications, distinguishing it from standard consumer-grade op-amps. It shares core electrical characteristics with other members of the BD728x series but offers a quad-channel configuration in a specific surface-mount package.

Replacement Considerations

Direct substitutes may include other quad-channel rail-to-rail op-amps with similar GBW and slew rates, such as those from the BD7285FV-LB series if pinout compatibility allows. Verify that any replacement maintains the Nano Cap™ stability feature or includes external compensation if driving large capacitors. Ensure the alternative package matches the SOP-J14 dimensions for board-level interchangeability.
