BU7242SNUX-TR

Overview

The BU7242SNUX-TR is a dual general-purpose operational amplifier manufactured by ROHM Semiconductor. It operates on a single supply voltage ranging from 1.8 V to 5.5 V. Key electrical parameters include a gain-bandwidth product of 900 kHz, a slew rate of 400 mV/µs, and an input offset voltage of 1 mV. The device draws a typical operating current of 180 µA per channel and provides an output current of 10 mA. It features a common-mode rejection ratio of 45 dB and a power supply rejection ratio of 60 dB. The component is housed in a VSON-8 surface-mount package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Supports full amplitude input and output voltage swings within the supply rails.
• Features extremely low input bias current for high-impedance signal applications.
• Integrates internal phase compensation capacitors to simplify circuit design.
• Operates efficiently with low supply current consumption.

Applications

• Low voltage portable electronic devices
• Battery-powered instrumentation circuits
• Signal conditioning for sensor interfaces

Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the VSON-8 footprint matches the PCB layout requirements. Check for any regional export control classifications or material restriction declarations relevant to the procurement destination.

Selection Notes

Select this component for designs requiring low power consumption with rail-to-rail output capabilities. The wide operating temperature range makes it suitable for industrial environments. Consider the 900 kHz bandwidth limit when designing for higher frequency signal processing tasks. Verify that the 10 mA output drive capability meets the load requirements of the downstream circuitry.

Part Context

This part belongs to the BU7242 series of low-power CMOS operational amplifiers. The series is characterized by monolithic integration of full-swing op-amp circuits with built-in phase compensation. It is designed for applications demanding low voltage operation and minimal current draw, distinguishing it from standard bipolar op-amps.
