BU7244SFV-E2

Overview

The BU7244SFV-E2 is a low power input-output full swing operational amplifier manufactured by ROHM Semiconductor. It features four channels in an SSOP-B14 package. Key electrical parameters include a gain-bandwidth product of 900 kHz, a slew rate of 4 V/us, and an input offset voltage of 1 mV. The device operates on a supply voltage range from 1.8 V to 5.5 V with a typical circuit current of 360 uA. It supports an output current of 10 mA per channel and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Low power consumption suitable for battery-operated applications
• Full swing input and output voltage ranges
• Very low input bias current characteristics
• Integrated phase compensation capacitors

Applications

• Portable electronic devices
• Sensor signal conditioning circuits
• Low voltage analog processing systems

Procurement Notes

Verify the specific suffix E2 for RoHS compliance and lead time requirements. Confirm the SSOP-B14 package dimensions against PCB footprint specifications. Ensure the operating temperature range meets system environmental constraints. Check for automotive qualification restrictions as this is a standard-grade product not recommended for vehicle use.

Selection Notes

Select this component when full rail-to-rail input and output capability is required at low supply voltages. The low quiescent current makes it suitable for energy-efficient designs. Consider the 900 kHz bandwidth for moderate speed signal amplification tasks. Verify that the 10 mA output drive capability meets load requirements without external buffering.

Part Context

This part belongs to the BU7244 series of low voltage CMOS operational amplifiers. It shares functional similarities with other members like the BU7244F-E2 but differs in package type and thermal performance. The series is designed for single-supply operation in compact consumer electronics where space and power efficiency are critical design constraints.

Replacement Considerations

BU7244F-E2 offers similar electrical performance in a SOP-14 package. BU7244SF provides the same functionality in a non-E2 variant. Verify pin compatibility and thermal characteristics when substituting.
