Reference Voltage ICs for PLCs

A voltage reference produces a constant level of voltage over time regardless of load, changes in power supply, or temperature. Voltage references are used in power supplies, analog-to-digital converters, digital-to-analog converters, and many other applications where voltage levels must be maintained at a steady level.
