Voltage dividers and voltage references provide highly-accurate reference voltages for calibration and testing purposes. Voltage dividers produce an output voltage (Vout) that is proportional to an input voltage (Vin). They consist of a series of fixed resistors (R1 and R2) that function as a highly accurate, variable potentiometer. Kelvin-Varley devices, a type of voltage divider, use a bridge circuit with two standard-value resistors. The ratio of the resistance value determines the voltage or current ratio. Operating specifications for voltage dividers and voltage references include temperature coefficient, operating temperature, and stability. Voltage and current specifications for voltage dividers and voltage references include input voltage range, output voltage range, voltage accuracy, voltage resolution per step, current range, current accuracy, and current resolution per step.
