BU7244F-E2

Overview

The BU7244F-E2 is a low power input-output full swing operational amplifier manufactured by ROHM Semiconductor. It features four channels in an SSOP-B14 package, operating within a supply voltage range of 1.8V to 5.5V. The device draws a typical circuit current of 0.09mA per channel and supports an operating temperature range from -40°C to 105°C. Input voltage ranges from VSS to VDD, while the output swings from VSS+0.1V to VDD-0.1V. The maximum input offset voltage is specified at 8.5mV.

Feature Summary

• Low power consumption with minimal current draw per channel
• Full swing input and output capabilities for extended dynamic range
• Integrated phase compensation capacitors for stability
• Very low input bias current characteristics

Applications

• Battery-powered portable devices
• Sensor signal amplification circuits
• Low voltage analog processing systems

Procurement Notes

Verify the specific suffix E2 against the official datasheet to confirm RoHS compliance and lead-free status. Ensure the SSOP-B14 package dimensions match the design constraints. Confirm the operating temperature range requirements align with the -40°C to 105°C specification before finalizing procurement orders.

Selection Notes

Select this component when low quiescent current and rail-to-rail performance are required in a compact surface-mount package. The four-channel configuration allows for multiple signal paths in a single footprint. Verify that the 1.8V minimum supply voltage meets the system's power budget and that the 8.5mV max offset voltage satisfies precision requirements.

Part Context

This part belongs to the BU7244 series of CMOS operational amplifiers designed for low voltage applications. It integrates four independent amplifiers with built-in phase compensation on a single chip. The series emphasizes low power operation and full swing I/O, making it suitable for battery-driven equipment where efficiency and space are critical factors.

Replacement Considerations

Check for BU7244SFV-E2 as a potential alternative with similar specifications but verify package compatibility between SSOP-B14 variants.
