Overview
The BA3474FVJ-E2 is a high-speed operational amplifier manufactured by ROHM Semiconductor, featuring four independent channels in a TSSOP-B14J package. It operates on a wide single power supply voltage range of +3.0 V to +36.0 V or dual supplies of ±1.5 V to ±18.0 V. Key electrical parameters include a typical gain-bandwidth product of 4 MHz and a slew rate of 10 V/µs. The device supports ground-sensed input and output, with an input offset voltage maximum of 10 mV and a typical circuit current of 2 mA per channel.
Feature Summary
- Supports operation with a single power supply across a wide voltage range from +3.0 V to +36.0 V.
- Features high-speed performance with a typical slew rate of 10 V/µs and a gain-bandwidth product of 4 MHz.
- Enables ground-sensed input and output capabilities for flexible signal interfacing.
Applications
- Full DC brushless fan control circuits
- High-speed signal processing applications
- General-purpose analog amplification
Procurement Notes
Verify the specific suffix 'E2' against the manufacturer's latest documentation to confirm compliance with current environmental standards and pinout configurations. Confirm availability status as this component may be subject to production lifecycle changes. Ensure the TSSOP-B14J package dimensions match the target PCB footprint requirements before finalizing procurement decisions.
Selection Notes
Select this component when a high-speed, multi-channel operational amplifier is required for single-supply systems operating up to 36 V. Consider its ground-sense capability for applications requiring input signals near the negative rail. Evaluate the 4 MHz bandwidth and 10 V/µs slew rate against signal frequency requirements to ensure adequate performance margins for the intended application dynamics.
Part Context
This part belongs to the BA3474 series of high-speed operational amplifiers from ROHM Semiconductor. It is designed for applications requiring multiple channels with high-speed response characteristics. The device integrates internal phase compensation capacitors, simplifying circuit design while maintaining stability across the specified operating temperature range of -40°C to +85°C.
Replacement Considerations
Check for direct substitutes within the BA3474 family or equivalent high-speed quad op-amps from other manufacturers. Verify pin compatibility and electrical parameter alignment, particularly regarding slew rate and supply voltage ranges, before implementing any alternative components.
