Overview
The AD7376ARUZ10, produced by Analog Devices Inc., is a high voltage, high performance digital potentiometer. This device is part of the AD7376 series, which offers 128-position digital control and can be used as a programmable resistor or resistor divider. It provides the same electronic adjustment functions as mechanical potentiometers, variable resistors, and trimmers, but with enhanced resolution, solid-state reliability, and programmability. The AD7376 is particularly useful for applications requiring digital rather than manual control, offering layout flexibility and closed-loop dynamic controllability.
