BU7244SF-E2

Overview

The BU7244SF-E2 is a low-power, input-output full swing operational amplifier manufactured by ROHM Semiconductor. It features four channels in a single package with a gain-bandwidth product of 900 kHz and a slew rate of 4 V/us. The device operates on a supply voltage range from 1.8 V to 5.5 V, drawing a typical operating current of 360 uA. Key electrical specifications include an input offset voltage of 1 mV, input bias current of 1 pA, common-mode rejection ratio of 45 dB, and power supply rejection ratio of 60 dB. Each channel provides an output current capability of 10 mA.

Feature Summary

• Low power consumption design suitable for battery-operated applications
• Input and output full swing capability for maximum dynamic range
• High precision performance with low input offset voltage and bias current

Applications

• Portable electronic devices requiring low power operation
• Signal conditioning circuits in sensor interfaces
• General-purpose analog signal processing

Procurement Notes

Verify the specific suffix E2 against the manufacturer's official datasheet to confirm pinout compatibility and environmental compliance status. Ensure the SOP-14 package variant matches your PCB footprint requirements. Cross-reference the RoHS status directly with the latest documentation provided by ROHM Semiconductor before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits that require rail-to-rail input and output swing within a single-supply voltage range. It is appropriate for applications demanding low quiescent current while maintaining adequate bandwidth for audio or slow-speed data acquisition. Consider the 10 mA output drive capability for driving moderate loads without external buffering stages.

Part Context

This part belongs to the BU7244SF series of operational amplifiers from ROHM Semiconductor. It is categorized as a low supply current amplifier designed for general-purpose use. The device integrates four independent amplifiers into a compact SOP-14 surface-mount package, offering a solution for space-constrained designs requiring multiple signal processing channels.
