Overview
The BA3472FV-E2 is a dual-channel high-speed operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 3 V to 36 V (single) or ±1.5 V to ±18 V (dual). Key electrical parameters include a gain-bandwidth product of 4 MHz, a slew rate of 10 V/µs, and an input offset voltage of 1 mV. The device draws 4 mA of operating current per channel and provides a typical output current of 30 mA. It features a common-mode rejection ratio of 60 dB and functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Supports wide single-supply operation from 3.0 V to 36.0 V
- Provides high-speed performance with a 10 V/µs slew rate
- Integrates internal phase compensation capacitors for stability
Applications
- General-purpose signal amplification circuits
- High-speed analog processing applications
- Ground-sense operational amplifier configurations
Procurement Notes
Verify the current lifecycle status before procurement, as this component may be designated as Not Recommended for New Designs (NRND). Confirm that the SSOP-B8 package dimensions align with your PCB footprint requirements. Ensure that the specified operating temperature range meets your environmental constraints. Cross-reference the datasheet for any specific handling precautions associated with the surface-mount technology.
Selection Notes
Select this component when a dual-channel amplifier requires high slew rates and wide voltage tolerance in a compact package. It is suitable for designs needing ground-sense capabilities without external compensation components. Consider the 4 MHz bandwidth limit for frequency-dependent applications. Evaluate the 1 mV input offset voltage against your precision requirements.
Part Context
This part belongs to the BA3472 series of high-speed operational amplifiers. It shares functional similarities with other ROHM dual-channel op-amps but is distinguished by its specific high-voltage tolerance and speed characteristics. The series is designed for applications requiring robust performance across varying supply voltages.
Replacement Considerations
Check for direct pin-compatible substitutes within the ROHM portfolio. Verify if alternative models offer improved lifecycle status or updated packaging options while maintaining equivalent electrical specifications.
