AD5201BRMZ50

AD5201BRMZ50 is a 33-position digital potentiometer. It can be digitally controlled through a 3-wire SPI serial interface. The terms programmable resistor, variable resistor (VR), and RDAC are commonly used interchangeably to refer to digital potentiometers. This device performs the same electronic adjustment function as a potentiometer or variable resistor. It contains a single variable resistor in the compact package. This device contains a fixed wiper resistance at the wiper contact that taps the programmable resistance at a point determined by a digital code. The code is loaded in the serial input register. It is used in applications such as mechanical potentiometer replacement, instrumentation: gain, offset adjustment, programmable voltage-to-current conversion, programmable filters, delays, time constants, and line impedance matching.
