### Q: What are the main applications of programmable resistor networks in electronic manufacturing?
**A**: Programmable resistor networks are primarily used in amplification circuits where precise gain values need to be set digitally, including in audio equipment, instrumentation amplifiers, sensor interfaces, and communication systems where adjustable signal conditioning is required.

### Q: How do programmable resistor networks differ from traditional fixed resistor arrays?
**A**: Unlike fixed resistor arrays with predetermined values, programmable networks incorporate digital switches and control logic that allow users to dynamically configure resistance values through digital signals, enabling real-time adjustments without physical component changes.

### Q: What materials are typically used in high-performance programmable resistor networks?
**A**: High-performance networks use silicon substrates for integrated circuits, thin-film resistive materials like nickel-chromium (NiCr) or tantalum nitride (TaN) for stability and precision, and metal interconnects such as aluminum or copper for reliable electrical connections.
