根据机械电子工程类专业测控实验教学平台数据采集的需要，在综合考虑成本和性能基础上，提出以为主处理芯片的数据采集卡设计方案。 该方案的主要特点是，使用基于ARM7TDMI内核的，工作主频最高可达44MHz；内置高性能的ADC和DAC模块，采样速度最高可达1MSPS，采样精度为12位；模拟信号输入通道最多可达16路，模拟信号输出通 ...
模拟电子 应用笔记-校准激光驱动器POT和DAC
Abstract: A laser module designer can use a fixed resistor, mechanical pot, digital pot, or a digital-to-analogconverter (DAC) to control the laser driver's modulation and bias currents. The advantages of a programmablemethod (POT or DAC) are that the manufacturing process can be automated and ...
模拟电子 DAC技术用语 (D/A Converters Defini
Differential Nonlinearity: Ideally, any two adjacent digitalcodes correspond to output analog voltages that are exactlyone LSB apart. Differential non-linearity is a measure of theworst case deviation from the ideal 1 LSB step. For example,a DAC with a 1.5 LSB output change for a 1 LSB digital codec ...
