NAD was established in 1972, and over fifty years later, it continues to be at the forefront of product design and philosophy, bringing us many surprises through new technologies, such as this little black box we are discussing today—the NAD C700. 1. Usage Scenarios Overall dimensions: 218 x 96 x 266 mm. Upon first seeing … Read more
NEWS Click the blue words to follow us HangJing The core component responsible for digital-to-analog conversion in acoustic playback systems is the DAC chip. Since the 1970s, single-chip integrated circuit (IC) DACs have marked the beginning of the DAC chip era. Mainstream DAC Chips 1 AKM AKM is a Japanese chip manufacturer (Asahi Kasei Microdevices … Read more
After successfully reading the SD card with the SDIO module on STM32F4 at the end of last month (see: STM32 SDIO Troubleshooting), I finally implemented a simple FAT32 file system, and then read the WAV files on the card to output signals to my CS4398 DAC to play music. Despite being quite rudimentary, I have … Read more
I mentioned in a previous article about the information on outputting waveforms using the MDK built-in logic analyzer. I found that some people are interested in using the MDK built-in logic analyzer to implement waveform output. Below, I will use the STM32F334 DAC module to output an arbitrary waveform and display the waveform using the … Read more
1. Introduction Recently, I built an R2R ladder resistor DAC circuit using resistors with a precision of one thousandth. Through testing, the circuit achieved a linear accuracy of 12 bits. Now, I ponder a question: if I reduce the order of R2R, for example to 12 bits, what would its linear accuracy be? Below, I … Read more
01 DAC Trapezoidal Resistor 1. Introduction Yesterday, I tested the development toolchain for the STM32G431. Today, I plan to try some interesting experiments. I saw a friend share their R2R trapezoidal resistor DAC solution on Bilibili, and I became quite interested. Therefore, I decided to test the performance of the trapezoidal resistor DAC solution using … Read more
