BU7462SNUX-TR

Overview

The BU7462SNUX-TR is a dual ground-sense low-voltage CMOS operational amplifier manufactured by ROHM Semiconductor. It operates on a single power supply ranging from 1.7 V to 5.5 V, with a typical quiescent current of 0.15 mA per channel. The device features a gain-bandwidth product of 1 MHz and a slew rate of 1 V/µs. Input offset voltage is maximized at 6 mV, while input bias current is typically 0.001 nA. It utilizes a VSON008X2030 package measuring 2.0x3.0 mm.

Feature Summary

• Ground-sense input capability allowing operation down to the negative rail
• Full-swing output voltage range extending close to both supply rails
• Integrated phase compensation capacitors for stability without external components

Applications

• Low-voltage signal conditioning in portable battery-powered devices
• Sensor interface circuits requiring ground-referenced input signals
• Audio pre-amplification stages in consumer electronics
• Active filter implementations in compact mobile systems

Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging configuration. Confirm the VSON008X2030 footprint matches your PCB layout requirements. Ensure compliance with RoHS standards if required for your manufacturing process. Check for any automotive qualification restrictions as standard grade products may not be suitable for vehicle applications.

Selection Notes

Select this component when ground-referenced inputs are necessary within a low-voltage system. The 1.7 V minimum supply makes it suitable for single-cell battery applications. Compare against other ROHM series like BU7462SF-E2 if SOP-8 packaging is preferred over VSON. Consider the 8 mA output drive capability for driving moderate loads directly.

Part Context

This part belongs to the BU7462 series of high-speed ground-sense operational amplifiers. The series includes variants with one, two, or four amplifiers per chip. The SNUX designation specifically identifies the dual-channel version in the VSON008X2030 package. These amplifiers are designed for general-purpose use in low-voltage analog signal processing tasks.

Replacement Considerations

The BU7462SF-E2 is a recommended alternative offering similar electrical characteristics but in an SOP-8 package. Verify pin compatibility and thermal performance differences between VSON and SOP packages before substitution. Ensure the replacement meets the same ground-sense and full-swing requirements.
