The following eight bits are The AD5207 provides dual channel, 256-position, digitally the data bits that represent the 256 steps of the resistance value. controlled variable resistor (VR) devices that perform the same The reason for two address bits instead of one is to be compatible electronic adjustment function as a potentiometer or variable with similar products such as AD8402 so that drop-in replacement resistor. Each channel of the AD5207 contains a fixed resistor with is possible. The address bit determines the corresponding VR a wiper contact that taps the fixed resistor value at a point
