Voltage references are basic building blocks for ADCs and DACs, the key ingredients in measurement systems.
Voltage references are key components in analog-to digital converter circuits, digital-to-analog converter circuits, and power supplies. While they can be simple devices such as Zener diodes, voltage references have their specs that you must deal with when specifying them. This week's quiz is based on Voltage Reference
Selection Basics, an application note from Texas Instruments. The last question is based on a figure in the book Current Sources & Voltage References by Linden T. Harrison.
1. Like nearly all analog circuits, voltage references have temperature-coefficient (TC) specification. Which of the following units is used to specify TC?
