AD5201 - Analog Devices

AD5201 256-Position and 33-Position Digital Potentiometers

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 commonly used interchangeably to refer to digital potentiometers. These devices perform the same electronic adj.
