Shunt Voltage References
Analog Devices offers a broad line of shunt precision voltage references that combine excellent accuracy and temperature stability with low noise and small packages. These devices operate in a manner that is functionally equivalent to a Zener diode. The bias current must be set higher than the sum of the maximum quiescent current of the voltage reference and the maximum expected load current. Since shunt voltage references are typically biased with a resistor, the voltage reference can operate on a wide range of input voltages.
