Digital-to-Analog (DAC), Analog-to-Digital (ADC) Converter Circuits Explained

Last Updated on May 20, 2026 by Swagatam 4 Comments

ladder formula

A digital-to-analog converter (DAC, D/A, D2A, or D-to-A) is a circuit designed to convert a digital input signal into an analog output signal. The analog-to-digital converter (ADC) works in the opposite way and transforms an analog input signal into a digital output. In this article I will comprehensively discuss how digital to analog, and analog to digital converter circuits work, using diagrams and formulas. In […]
