Overview
The BU7244FV-E2 is a low-power, input-output full-swing operational amplifier manufactured by ROHM Semiconductor. It features four channels in an SSOP-14 package. Key electrical parameters include a gain-bandwidth product of 900 kHz and a slew rate of 4 V/us. The input offset voltage is 1 mV, with an input bias current of 1 pA. It operates on a supply voltage range from 1.8 V to 5.5 V, consuming 360 uA per channel. Each channel provides an output current of 10 mA. Common-mode rejection ratio is 45 dB, and power supply rejection ratio is 60 dB.
Feature Summary
- Supports full-swing input and output operation within the supply voltage range.
- Features extremely low input bias current for high-impedance applications.
- Designed for low-voltage operation with minimal power consumption.
Applications
- Battery-powered portable devices requiring low current draw
- Signal conditioning circuits in consumer electronics
- Sensor interface amplifiers
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Confirm that the SSOP-14 package dimensions match the target PCB footprint. Ensure the operating temperature range meets the system requirements. Cross-reference the part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when full-signal swing is required at both input and output nodes under single-supply conditions. It is suitable for designs prioritizing low quiescent current over high-speed performance. Compare the 900 kHz bandwidth against application signal frequencies. Consider the 1 pA bias current for high-impedance sensor interfaces.
Part Context
This device belongs to ROHM's low-power CMOS operational amplifier family. It integrates phase compensation capacitors internally, simplifying circuit design. The BU7244 series includes variants with different channel counts and packages. The FV suffix typically denotes the SSOP-14 surface-mount package variant.
Replacement Considerations
Check for BU7244F (SOP-14) if through-hole packaging is acceptable. Verify BU7244SFV-E2 for extended temperature range requirements up to 105°C. Consult ROHM documentation for direct pin-compatible alternatives within the same series.
