Working Principles

AD5143BCPZ10-RL7 utilizes a digital-to-analog converter (DAC) and a resistor network to generate the desired resistance value. The digital control interface allows the user to set the resistance digitally, which is then converted into an analog signal using the DAC. The resulting analog signal is fed into the resistor network, which adjusts the overall resistance value accordingly.
