BU7241G-TR

Overview

The BU7241G-TR is a single-channel, low-voltage CMOS operational amplifier manufactured by Rohm Semiconductor. It operates within a supply voltage range of 1.8 V to 5.5 V and features full-swing input and output capabilities. Key electrical specifications include a typical supply current of 70 µA per channel, an input bias current of 1 pA, and an input offset voltage of 1 mV. The device offers a gain-bandwidth product of 900 kHz, a slew rate of 0.4 V/µs, and can deliver an output current of 12 mA. It is housed in a 5-SSOP (SC-74A) surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Full-signal swing capability at both the input and output terminals across the entire supply voltage range.
• Ultra-low power consumption with minimal supply current requirements suitable for battery-operated systems.
• High input impedance characterized by extremely low input bias current levels.

Applications

• Low-power sensor signal conditioning circuits
• Portable electronic devices requiring extended battery life
• General-purpose analog signal processing

Procurement Notes

Verify the specific ordering suffix to confirm the packaging format, such as tape-and-reel quantities. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure the selected variant matches the required operating temperature range and pinout configuration for the target PCB layout.

Selection Notes

Select this component when full input and output voltage swing is required under low supply voltages. Consider the 1 mV input offset voltage and 900 kHz bandwidth for precision applications. Evaluate the 5-SSOP package constraints against available board space and thermal management requirements.

Part Context

This part belongs to the BU7241 series of low-voltage CMOS operational amplifiers. The series includes variants with one, two, or four channels, all sharing similar electrical characteristics such as low supply current and full-swing operation. The BU7241G-TR specifically denotes the single-channel version in tape-and-reel packaging.

Replacement Considerations

Check for direct substitutes within the same family, such as the BU7241SG-TR, which shares identical electrical specifications but may differ in packaging or minor manufacturing revisions. Verify pin compatibility before substitution.
