The AD5280/AD5282 provides a single/dual channel, 256 position digitally-controlled variable resistor (VR) device. These devices perform the same electronic adjustment function as a potentiometer, trimmer or variable resistor. Each VR offers a completely programmable value of resistance, between the A terminal and the wiper, or the B terminal and the wiper. The fixed A-to-B terminal resistance of 20, 50 or 200K ohms has a 1% channel-to-channel matching tolerance with a nominal temperature coefficient of 30 ppm/C.
