Most of the signals around us, in the world we live in are not digital in nature, rather they are analog. The digital systems can understand only digital signals, not analog. Hence, it becomes important to interface the digital systems we the external analog world. The analog input signals are to be converted to digital signals using Analog to Digital Converters at the input end of the digital system. After the processing by the system, the digital signals are to be converted back into analog signals using Digital to Analog Converters.
A n-bit Digital to Analog Converter (DAC) takes a n-bit digital word and converts it into a proportional analog voltage with respect to the reference voltage. The potentiometric DAC uses the concept of Voltage Divider. In an N-bit DAC, the analog voltage range, i.e. the Vref (here 3.3 V) is equally divided into 2^N voltage values. This is achieved by a series on 2^N equal resistors and taps are provided across each R. The combination of switches to tap the values is designed using the N-bit digital word as input.
This circuit was designed using eSim
eSim (previously known as Oscad / FreeEDA) is a free/libre and opensource EDA tool for circuit design, simulation, analysis and PCB design. It is an integrated tool built using free/libre and opensource software such as KiCad, Ngspice and GHDL. eSim is released under GPL.
eSim offers similar capabilities and ease of use as any equivalent proprietary software for schematic creation, simulation and PCB design, without having to pay a huge amount of money to procure licenses. Hence it can be an affordable alternative to educational institutions and SMEs. It can serve as an alternative to commercially available/licensed software tools like OrCAD, Xpedition and HSPICE.

Detailed Analysis
CourseMarks Score®
CourseMarks Score® helps students to find the best classes. We aggregate 18 factors, including freshness, student feedback and content diversity.
Freshness Score
Course content can become outdated quite quickly. After analysing 71,530 courses, we found that the highest rated courses are updated every year. If a course has not been updated for more than 2 years, you should carefully evaluate the course before enrolling.
Student Feedback
New courses are hard to evaluate because there are no or just a few student ratings, but Student Feedback Score helps you find great courses even with fewer reviews.
Content Score
The top online course contains a detailed description of the course, what you will learn and also a detailed description about the instructor.
Tests, exercises, articles and other resources help students to better understand and deepen their understanding of the topic.
