GENERAL DESCRIPTION
●The AD5207 provides dual channel, 256-position, digitally controlled variable resistor (VR) devices that perform the same electronic adjustment function as a potentiometer or variable resistor. Each channel of the AD5207 contains a fixed resistor with a wiper contact that taps the fixed resistor value at a point determined by a digital code loaded into the SPI-compatible serial-input register.
