What are the key features of LF347BNE4?

Quad JFET-input op-amp with ultra-low bias current of 0.0002 µA max for high-impedance sensor interfaces
Wide ±18 V supply voltage range with 100 dB typical CMRR for precision differential signal processing
Internal frequency compensation with voltage-feedback architecture in through-hole 14-pin PDIP for easy prototyping

What is LF347BNE4 used for?

The LF347BNE4 is well-suited for precision signal conditioning, active filtering, and instrumentation amplifier circuits where ultra-low input bias current is essential. Its quad configuration makes it ideal for multichannel audio processing, sensor signal amplification, and sample-and-hold circuits. The wide supply voltage range and high CMRR also make it suitable for industrial data acquisition front-ends and precision voltage-to-current converters.

Frequently Asked Questions

For a new board, how does the 18 V parameter affect use of LF347BNE4?

The fetched product context identifies LF347BNE4 with 18 V. Engineers should confirm this concrete value against the manufacturer datasheet and verify that electrical limits, board interfaces, and system requirements match the intended design.

Before production release, which footprint and assembly checks are important for LF347BNE4?

Production teams should verify the footprint, orientation, and assembly method against controlled drawings. The recorded 18 V characteristic provides a concrete checkpoint before PCB release, first-article inspection, and volume manufacturing.

During procurement qualification, what should buyers verify for LF347BNE4 and approved alternatives?

Buyers should match the complete orderable MPN and manufacturer documentation, while confirming that the required 18 V configuration remains consistent across quoted stock, approved alternatives, and incoming inspection records.
