Overview
The BA3472F-E2 is a dual-channel high-speed ground-sense operational amplifier manufactured by ROHM Semiconductor. It operates on a single power supply ranging from 3.0V to 36.0V, or dual supplies of ±1.5V to ±18.0V. Key electrical parameters include a typical gain-bandwidth product of 4MHz, a slew rate of 10V/µs, and an input bias current of 100nA. The device features a maximum input offset voltage of 10mV and provides a typical output current of 30mA. It is housed in an SSOP-B8 package with dimensions of 3.0x6.4mm.
Feature Summary
- Supports wide operating supply voltage ranges for flexible system integration
- Enables ground sensing capabilities through specific input voltage range characteristics
- Integrates internal phase compensation capacitors for stability
Applications
- High-speed signal processing circuits
- Ground-referenced sensor interface applications
- General-purpose analog amplification systems
Procurement Notes
Verify the current lifecycle status before design finalization, as this component may be marked as not recommended for new designs. Confirm that the SSOP-B8 package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check for any specific handling precautions related to the taping packaging format during assembly.
Selection Notes
Select this component when a dual-channel op-amp with high slew rate and ground-sense capability is required within a wide voltage range. Consider the 4MHz bandwidth and 10V/µs slew rate for speed-sensitive applications. Evaluate the 100nA input bias current against noise requirements. Compare the SSOP-B8 package size against available board space constraints relative to other SOIC or TSSOP alternatives.
Part Context
This part belongs to the BA3472 series of high-speed operational amplifiers designed by ROHM Semiconductor. The series focuses on providing high gain and fast response times suitable for demanding analog applications. The BA3472F-E2 variant specifically utilizes the SSOP-B8 package configuration, distinguishing it from other pinout or package variations within the broader family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct functional equivalents only after consulting official manufacturer cross-reference lists.
