BU7241SG-TR

Overview

The BU7241SG-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 consumes a typical quiescent current of 70 µA per channel. Key electrical specifications include a gain-bandwidth product of 900 kHz, a slew rate of 0.4 V/µs, and an input offset voltage of 1 mV. The device features rail-to-rail input and output capabilities, with an output swing extending from VSS+0.1 V to VDD-0.1 V. It provides a typical open-loop voltage gain of 95 dB and supports an output current of 10 mA. The component is housed in an SSOP-5 package and is rated for operation between -40°C and +105°C.

Feature Summary

• Supports low-voltage operation ranging from 1.8 V to 5.5 V with minimal power consumption.
• Enables full-amplitude signal processing through rail-to-rail input and output voltage swings.
• Integrates internal phase compensation capacitors to simplify circuit design without external components.
• Maintains stable performance across a wide industrial temperature range from -40°C to +105°C.

Applications

• Battery-powered portable electronic devices requiring extended operational life.
• Low-power sensor signal conditioning circuits.
• Single-supply analog signal processing systems.
• Consumer electronics utilizing limited voltage headroom.

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity of 3000 units. Confirm that the SSOP-5 package dimensions align with the target PCB footprint. Ensure the selected variant meets the necessary RoHS compliance standards for the intended market. Cross-reference the manufacturer part number against official datasheets to confirm pinout compatibility before finalizing procurement orders.

Selection Notes

Select this component when designing circuits constrained by low supply voltages below standard 5 V thresholds. It is suitable for applications prioritizing low static current draw over high-speed signal amplification. Consider its rail-to-rail characteristics for maximizing dynamic range in single-supply environments. Evaluate the 900 kHz bandwidth limit to ensure it suffices for the target signal frequencies.
