AD5200 Description
The AD5200 and AD5201 are programmable resistor devices, with 256 positions and 33 positions respectively, that can be digitally controlled through a 3-wire SPI serial interface. The terms programmable resistor, variable resistor (VR), and RDAC are monly used interchangeably to refer to digital potentiometers. These devices perform the same electronic adjustment function as a potentiometer or variable resistor.
