THEORY OF OPERATION The AD5243/AD5248 are 256-position, digitally controlled variable resistor (VR) devices. An internal power-on preset places the wiper at midscale during power-on, which simplifies the fault condition recovery at power-up. PROGRAMMING THE VARIABLE RESISTOR AND VOLTAGE Rheostat Operation ...
