Potentiostat / galvanostat with digital interface

摘要

The potentiostat / galvanostat uses a controller that provides a digital control signal to a digital-to-analog converter (DAC) that generates an analog output signal in response to the digital control signal. The large current driver generates a large current output in response to an analog output signal from the DAC. The high current monitor monitors the output of the high current driver, generates a feedback signal for the high current driver to control the current generated by the high current driver, and provides it from the high current driver for monitoring by the controller Produces an output that depends on the current being applied. A counter electrode contact for the counter electrode is connected to the output of the high current monitor. The working electrode for the working electrode is electrically connected to a fixed and stable potential, allowing electrochemical analysis of the material between the counter electrode and the working electrode.
