BU7241YG-CGTR

Overview

The BU7241YG-CGTR is a single-channel CMOS operational amplifier designed for low-voltage applications. It operates within a supply voltage range of 1.8 V to 5.5 V and features full-swing input and output capabilities. The device draws a typical supply current of 70 µA per channel and supports an output current of 15 mA. Key electrical parameters include a gain-bandwidth product of 1 MHz, a slew rate of 0.42 V/µs, and a maximum input offset voltage of 1 mV. It exhibits a typical input bias current of 1 pA and functions reliably across a temperature range of -40°C to 125°C.

Feature Summary

• AEC-Q100 qualified for automotive reliability standards
• Full-swing input and output operation at low voltages
• Ultra-low supply current consumption
• Minimal input bias current for high-impedance sensing

Applications

• Battery-powered electronic devices
• Sensor signal amplification circuits

Procurement Notes

Verify the complete part number including the suffix CGTR to ensure correct packaging and automotive qualification. Confirm that the specific revision matches the design requirements for voltage ranges and temperature ratings. Cross-reference the datasheet specifications against the application's power constraints and signal integrity needs before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring rail-to-rail performance under strict power budgets. The low quiescent current makes it suitable for battery-operated systems where energy efficiency is critical. Ensure the load requirements do not exceed the specified output current limits while maintaining the desired bandwidth and slew rate performance.

Part Context

This component belongs to the BU7241 series of low-voltage CMOS operational amplifiers manufactured by Rohm Semiconductor. The series includes variants with different package options and channel counts. The BU7241YG-CGTR specifically denotes the single-channel version in a 5-SSOP package, tailored for space-constrained automotive and industrial applications requiring high reliability.

Replacement Considerations

BD5241G-1 is listed as a similar level replacement with the same pinout and package, though it serves as a voltage detector rather than an op-amp. Verify functional equivalence carefully as direct substitution may require circuit redesign.
