Click the blue text Follow us Introduction: From Concept to Reality, DAC Enters the Acceleration Track Against the backdrop of the “dual carbon” strategy, a negative carbon technology capable of directly capturing carbon dioxide from the atmosphere—DAC (Direct Air Capture)—is becoming a new strategic pivot for energy transition and carbon management in various countries. It … Read more

Recently, I came across a project that captures carbon dioxide directly from the atmosphere, which was quite shocking. China’s annual carbon emissions reach 14 billion tons, and the concentration of carbon dioxide in the atmosphere is 0.04% (400 ppm). Who thought of this brilliant idea to capture carbon from the air instead of focusing on … Read more
silly pid:113107781 by:paccha!! DAC (Digital to Analog Converter, 数模转换器) DAC 基础部分 The function of a DAC is to convert digital signals into analog signals. The working principle of a DAC is the opposite of that of an ADC. A DAC can convert digital signals into analog signals for output and control. DACs have a wide … Read more
Written by｜Bomb Dance Everything started from an occasional thought in 2004 Earlier, I came across an interview with Bruno Putzeys, one of the founders of Mola Mola, in SoundStage! Ultra from 2014, which detailed the Mola Mola DAC that had not yet been officially launched at that time. Bruno mentioned that everything should start from … Read more
This article is about classic Q&A on ADC/DAC design, covering common issues such as clock duty cycle, common mode voltage, gain error, differential phase error, intermodulation distortion, and more. 1. What is Small Signal Bandwidth (SSBW)?Small Signal Bandwidth (SSBW) refers to the frequency at which the output amplitude drops to a specified value compared to … Read more
Any practical electronic application will be affected by multiple sources of error, which can cause even the most precise components to deviate from their specified behavior in the datasheet. When the application signal chain lacks built-in mechanisms to self-correct these errors, the only way to minimize their impact is to measure the errors and systematically … Read more
In the field of digital signal processing, the Nyquist sampling theorem establishes the fundamental criterion for signal digitization— to accurately reconstruct a continuous signal, the sampling frequency must be at least twice the highest frequency of the signal.However, engineers have observed an interesting phenomenon: in practical applications, we often generate signals exceeding 500MHz using a … Read more
The digital-to-analog (DAC) and analog-to-digital (ADC) conversion in microcontrollers is a key technology that connects digital systems with the analog world. 1. Basic Concepts 1. DAC (Digital-to-Analog Converter) Function: Converts digital signals into analog signals (such as voltage or current). Application Scenarios: Driving motors, audio output, LED dimming, etc. Implementation Methods: Weighted resistor networks, R-2R … Read more
