The AD5262BRUZ200 is a 2-channel 256-position SPI Compatible 15V Digital Potentiometer that performs the same electronic adjustment function as potentiometer or variable resistor. Each channel of the AD5262 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. The resistance between the wiper and either end point of the fixed resistor varies linearly with respect to the digital code transferred into the VR latch. The variable resistor offers a completely programmable value of resistance, between the A terminal and the wiper or the B terminal and the wiper. Unlike the majority of the digital potentiometers, this potentiometer can operate up to 15V or ±5V provided proper supply voltages are furnished. Each VR has its own VR latch that holds its programmed resistance value.
