The precision of a high-resolution successive-approximation ADC depends on the accuracy, stability, and drive capability of its voltage reference. The reference sees a dynamic load, so it must be able to handle time- and throughput-dependent currents. The best performance can usually be achieved with an external reference, so this article looks at the challenges and design requirements.
