BD7280YG-CTR

Overview

The BD7280YG-CTR is a single-channel, rail-to-rail input/output CMOS operational amplifier designed for automotive applications. It features high slew rate, low noise, and low input bias current. Key electrical parameters include a typical gain-bandwidth product of 7 MHz, a typical 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 supports an operating temperature range from -40°C to 125°C and meets AEC-Q100 standards.

Feature Summary

• Integrates Nano Cap™ technology to ensure stable operation without oscillation even when connected to output capacitors as small as 1 nF.
• Provides rail-to-rail input and output capabilities with high slew rate and low noise characteristics suitable for precision signal processing.
• Engineered for automotive environments with wide operating temperature range and compliance with functional safety support categories.

Applications

• Engine control units
• Electric Power Steering (EPS) systems
• Anti-lock Braking System (ABS) sensor amplifiers

Procurement Notes

Verify the specific suffix 'CTR' indicates the tape and reel packaging configuration containing 3000 units per reel. Confirm that the component status is listed as recommended for new designs. Ensure the RoHS compliance declaration matches current regulatory requirements for the target market. Cross-reference the SSOP6 package dimensions against the mechanical drawing in the official datasheet to verify footprint compatibility during procurement validation.

Selection Notes

Select this component when designing circuits requiring high-speed signal amplification with minimal noise interference in automotive environments. The Nano Cap™ feature simplifies design by eliminating the need for complex compensation networks typically required for capacitive loads. Consider the 1.7 mA quiescent current consumption relative to system power budgets. Verify that the 50 mA output current capability meets the drive requirements of the downstream load or sensor interface.

Part Context

This part belongs to ROHM's Nano Cap™ series of automotive-grade operational amplifiers. These devices are characterized by their ability to drive small capacitive loads stably, a common challenge in modern sensor interfaces. The BD7280 variant specifically offers a single-channel configuration within this family, providing a compact solution for applications where space is limited but performance specifications such as bandwidth and slew rate remain critical.

Replacement Considerations

Consult official substitution lists for direct equivalents. Generic replacements may not replicate the Nano Cap™ stability with small capacitive loads. Verify pinout compatibility and electrical parameter margins before integrating alternative components into existing automotive designs.
