Voltage Reference

A voltage reference is a stable, precise source of voltage used in electronic devices to ensure accurate measurements and operation. Think of it as a benchmark that provides a constant "electric pressure," much like a reference point in a map, against which other voltages are measured. Because it remains steady regardless of changes in temperature, load, or power supply, it allows meters, sensors, and circuits to function reliably and produce accurate results. In essence, it sets a consistent standard so the device's readings or performance don't drift over time or under different conditions.
