AD5200BRMZ10 (ANALOG DEVICES)

The AD5200BRMZ10 is a programmable Digital Potentiometer for use with mechanical potentiometer replacement. 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. Both AD5200 contain a single variable resistor. 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 code is loaded in the serial input register. 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. Each variable resistor offers a completely programmable value of resistance, between the A terminal and the wiper or the B terminal and the wiper.
