Selecting the Right Series Voltage Reference for Absolute-Accuracy Voltage-Output DAC Designs
Overview
When designing a system that includes a digital-to-analog converter (DAC) and an external voltage reference, the voltage-reference specifications are as important as the specifications of the DAC itself. This article explores some of the issues involved with selecting external, three-terminal series voltage references for voltage-output DACs. Examples of DAC system designs are used to illustrate the various trade-offs when optimizing for cost, accuracy, or power.
The main focus of this article is Maxim's three-terminal, series, bandgap voltage references, although buried-zener references are discussed as well. Two-terminal, shunt references are not covered, because three-terminal, series devices are now available at competitive prices and with low quiescent current that is virtually constant versus input voltage.
