Overview
The BA14741FJ-GE2 is a low noise operational amplifier manufactured by Rohm Semiconductor. It features four independent circuits in a 14-SOPJ package. Key electrical parameters include a gain bandwidth product of 2 MHz, a slew rate of 1 V/µs, and an output current of 20 mA per channel. The device operates on a single supply voltage range of 4V to 36V or dual supplies of ±2V to ±18V. The operating temperature range extends from -40°C to +85°C.
Feature Summary
- Low noise operational amplifier design
- Four independent amplifier circuits
- Wide single or dual power supply operation
Applications
- General purpose amplification
- Audio signal processing
- Sensor interface circuits
Procurement Notes
Verify the specific suffix GE2 for RoHS compliance and lead time requirements. Confirm the SOP-J14 package dimensions match the PCB footprint. Check for obsolescence notices as some sources indicate potential end-of-life status for this component family. Ensure the supplier provides official datasheets for final verification before integration.
Selection Notes
Select this component for applications requiring low noise performance with multiple channels. Compare the 2 MHz gain bandwidth against higher speed alternatives if signal fidelity at higher frequencies is critical. Verify that the 20 mA output current meets load requirements. Consider the 14-pin surface mount package constraints during layout design.
Part Context
This part belongs to Rohm's general-purpose operational amplifier lineup. It is designed for cost-sensitive applications requiring multiple channels in a compact surface mount package. The device serves as a standard solution for basic analog signal conditioning tasks where ultra-high speed is not required.
Replacement Considerations
Check for direct pin-compatible substitutes within the same manufacturer family. Verify equivalent electrical specifications such as gain bandwidth and input offset voltage when selecting third-party replacements. Ensure the replacement package matches the 14-SOPJ form factor.
