Voltage Reference
Microchip voltage reference devices produce a fixed (constant) voltage irrespective of the loading on the device, power supply variations, temperature changes, and the passage of time. Voltage references are used in/with power supplies, analog-to-digital converters, digital-to-analog converters, and other measurement and control systems. Voltage references vary widely in performance; a regulator for a computer power supply may only hold its value to within a few per cent of the nominal value, whereas laboratory voltage standards have precisions and stability measured in parts per million.
