Line Impedance Matching GENERAL 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
commonly used interchangeably to refer to digital potentiometers.
These devices perform the same electronic adjustment function
as a potentiometer or variable resistor. Both AD5200/AD5201
contain a single variable resistor in the compact MSOP
package. Each device contains a fixed wiper resistance at the
wiper contact that taps the programmable resistance at a point …
