BU7462NUX-TR

Overview

The BU7462NUX-TR is a dual-channel ground sense low voltage operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 1.7 V to 5.5 V and consumes a typical operating current of 300 µA. The device features a gain-bandwidth product of 1 MHz, a slew rate of 1 V/µs, and an input offset voltage of 1 mV. With an input bias current of 1 pA and output current capability of 8 mA per channel, it supports differential inputs in a VSON-8 package suitable for surface mount applications across a temperature range of -40°C to +85°C.

Feature Summary

• Ground sense input and full amplitude output operation
• Low voltage operation with minimal power consumption
• Integrated phase compensation capacitors

Applications

• Battery-powered portable devices requiring low quiescent current
• Signal conditioning circuits in single-supply systems
• Sensor interface amplification with ground-referenced inputs
• General-purpose analog signal processing in consumer electronics

Procurement Notes

Verify the specific manufacturer datasheet for the BU7462NUX-TR to confirm RoHS compliance status and exact electrical parameters at your operating conditions. Ensure the VSON-8 package dimensions match your PCB footprint design requirements before finalizing component selection.

Selection Notes

Select this component when a dual op-amp with ground-sense input capability is required for low-voltage single-supply designs. Consider the 1 MHz bandwidth and 1 V/µs slew rate for moderate-speed applications. Verify that the 8 mA output current meets load requirements and that the VSON-8 package is compatible with your assembly process.

Part Context

The BU7462NUX-TR belongs to the BU7462 series of CMOS operational amplifiers from ROHM Semiconductor. This series includes variants with different packaging options such as MSOP-8, designed for general-purpose applications where low power consumption and ground-sense functionality are critical. The NUX suffix specifically denotes the VSON-8 package type.

Replacement Considerations

Consult official ROHM documentation to identify qualified replacement parts. Direct substitutes must maintain identical pinout, electrical characteristics, and package dimensions. Verify compatibility with existing circuit designs before implementation.
