ANALOG DEVICES AD5200BRMZ50-REEL7

AD5200 is a programmable resistor device with 256 position. 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 perform the same electronic adjustment function as a potentiometer or variable resistor. It contain a single variable resistor in the compact package. Each device contains a fixed wiper resistance at the wiper contact that taps the programmable resistance at a point determined by a digital code. The resistance between the wiper and either end point of the programmable resistor varies linearly with respect to the digital code transferred into the VR latch. It is widely used in application such as mechanical potentiometer replacement, instrumentation: gain, offset adjustment, programmable voltage-to-current conversion, programmable filters, delays, time constants, line impedance matching etc.
