This reference design presents a four-quadrant discrete floating Voltage and Current (VI) design. Voltage output supports ±40V and 0V to 80V ranges, with three current ranges of 500mA, 10mA, and 10μA. The design operates on force voltage (FV), force current (FI), Buffer, and Gang mode with analog feedback loop. With 20-bit force digital-to- analog converter (DAC) and 18-bit, 2-channel analog- to-digital converter (ADC) and precision signal chain, the reference design achieves 0.01% accuracy for controlling and measuring after calibration.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
