Voltage References

(Showing 22 of 22)

A voltage reference IC is an electronic component or circuit that produces a fixed DC (direct-current) output voltage regardless of variations in external conditions such as the loading on the device, temperature changes, barometric pressure, humidity, current demand, or the passage of time. Voltage references are used in power supplies, analog-to-digital converters, digital-to-analog converters, and other measurement and control systems.
