摘要
介绍一种可预置输出、步进调整、数字显示的数控直流电流源。经测试表明,其电流调整步进可达1mA,纹波电流≤0.2mA,最大误差小于3mA。系统具有功耗低、性能可靠、结构简单、使用直观方便的优点。
A sort of MCU digital control DC source which can pre-regulate output, step adjustment and display was introduced. Its step current adjustment can reach 1 mA, ripple current maximum is 0.2mA. The output offset current maximum is 3mA. The system has low energy consumption, reliable performance and simple structure.
