In addition to reducing emissions, can we also ‘capture’ the carbon dioxide that has already been produced? The answer is: Yes! CCUS and DAC technologies are becoming the ‘carbon capture tools’ to combat climate change. When we talk about addressing climate change, ’emission reduction’ is undoubtedly the core keyword. However, the reality is that some … Read more
In the long history of digital audio development, the evolution of DAC chip technology has always been an important force driving the industry forward. We have witnessed the transition from single-bit to multi-bit, from discrete architectures to highly integrated single-chip solutions, with each technological breakthrough redefining the limits of sound reproduction. In recent years, the … Read more
The goal of this design is to produce an isolated DAC output. It requires a 12V power supply to generate an output of 0~5V, achieving approximately 13.3 bits of resolution at 10,000 counts. The DAC output must stabilize within 1 second after changing settings, and it should maintain stability and low noise over extended periods. … Read more
In the development history of smartphones, Smartisan Technology once entered the public eye with its unique sentiment and innovative concepts. On October 18, 2016, Smartisan Technology launched the Smartisan M1/M1L, which was supposed to be a highlight moment but became a regret in Luo Yonghao’s heart and a carrier of complex emotions for Hammer fans. … Read more
As a novice with only a basic understanding of parameters, my first standard for a player is that it sounds good. Recently, my new favorite, the QUAD-DAC powered Shanling M6 Ultra, left me stunned as soon as it started playing: the sound is relatively smooth and gentle, with slightly bright highs, emphasizing vocal performance and … Read more
The value of audio chips lies not only in their ability to “play sound” but also in whether they can make the sound feel “natural and comfortable.” A key component in this process is the DAC (Digital-to-Analog Converter). The music or speech we hear daily starts as digital signals of 0s and 1s within the … Read more
Optical modules, as the ‘micro core’ of optical communication systems, directly determine network bandwidth, transmission distance, and energy efficiency. From the ‘computing artery’ of data centers to the ‘information trunk’ of telecom networks, and into the ‘intelligent nervous system’ of industrial and automotive fields, optical modules have deeply integrated into every layer of the digital … Read more
Someone is using STM32F4 series chips to develop products and is using the DAC module. They discovered a strange phenomenon while using the DAC. They found that every time they used HAL_DAC_SetValue () to modify the output data, they also had to call HAL_DAC_Start () to output the corresponding DAC result. The code needs to … Read more
In high-end HiFi decoders, the digital-to-analog converter (DAC) chip is undoubtedly the “heart”. It determines how cold binary code is transformed into beautiful sound waves. Currently, the competition between Japan’s Asahi Kasei (AKM) and America’s ESS Technology has been ongoing for nearly a decade, with each having its unique advantages. This is far from a … Read more
This year, the AI computing hardware sector is booming — leading companies like Cambricon and Foxconn Industrial Internet are frequently hitting new highs, with daily transaction volumes in sub-sectors like optical modules and liquid cooling exceeding 10 billion. The underlying “blood vessels” supporting this computing power revolution — high-speed transmission cables such as AOC, DAC, … Read more
