Description: the system is Sunplus SPCE061A as the core controller, with current can be preset. Stepping can be adjusted to the current output signal and the current signal Preferences can also showed NC DC current source. Systems include : Sunplus SPCE061A streamline the development board, keyboard and display circuit, voltage-controlled current source circuit, Correction Circuit, and the power circuit. System through the keyboard keys on the current values of Preferences, Sunplus SPCE061A send the corresponding digital signal through D/A conversion, signal amplification, level translators, voltage-controlled current source, and the required output current; actual output current through precision resistor voltage signal into sampling, After high input impedance amplifier, A/D converters. feedback
