BD7542FVM-TR

Overview

The BD7542FVM-TR is a dual-channel CMOS operational amplifier manufactured by ROHM Semiconductor. It operates on a single supply voltage ranging from 5 V to 14.5 V, or dual supplies of ±2.5 V to ±7.25 V. The device features a gain-bandwidth product of 600 kHz and a slew rate of 300 mV/µs. Input offset voltage is typically 1 mV with an input bias current of 1 pA. Supply current per channel is 400 µA, delivering a typical output current of 4 mA. It utilizes an 8-MSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports high-voltage operation up to 14.5 V with low power consumption.
• Provides full input and output swing capabilities for maximum dynamic range.
• Integrates internal phase compensation capacitors to ensure stability without external components.

Applications

• High-voltage signal conditioning circuits
• Industrial sensor interface applications
• Battery-powered systems requiring wide voltage tolerance

Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging when ordering. Confirm the MSOP-8 package dimensions match your PCB footprint requirements. Ensure the operating environment stays within the specified -40°C to +85°C range. Check RoHS compliance status if required by your manufacturing standards. Validate that the 5 V minimum supply voltage aligns with your system's power rails.

Selection Notes

Select this component for designs requiring high-voltage tolerance in a compact surface-mount package. It is suitable for applications needing rail-to-rail performance without complex external compensation. Consider the 400 µA quiescent current for power-sensitive designs. Compare against lower-voltage alternatives if system supply exceeds 14.5 V.

Part Context

This part belongs to the BD7542 series of low-power, high-voltage CMOS operational amplifiers. The family includes single-channel variants like the BD7541 and other packages such as SOP-8. These devices are designed for robust performance in industrial and automotive environments where wide supply voltage ranges are necessary.

Replacement Considerations

Check for direct pin-compatible substitutes within the same ROHM series, such as the BD7541SFVM-TR for single-channel needs. Verify electrical parameters like slew rate and bandwidth against alternative manufacturers' parts to ensure functional equivalence in high-voltage applications.
