Cable Drop Compensation
Analog Devices cable drop compensation technology provides tight load regulation solutions for long, highly resistive cables without requiring an additional pair of remote sense wires. Members of this portfolio continuously interrogate line impedance and correct power supply output voltage via a feedback loop to maintain steady voltage at the load regardless of current changes. Our devices also includes precision, high-side current sense products with current-mode output that are designed for controlling the output voltage of an adjustable power supply or voltage regulator. This can be used to compensate for drops in voltage at a remote load due to resistance in a wire, trace, or cable.
