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
