AD5204 & AD5206 Digital Potentiometers

Analog Devices AD5204 (4-Channel) and AD5206 (6-Channel) Digital Potentiometers are 256-position digitally controlled variable resistor devices. Potentiometers are three-terminal resistors with sliding or rotating contacts that form an adjustable voltage divider. If two terminals are used (one end and the wiper), the potentiometer acts as a variable resistor. Each channel of the Analog Devices AD5204/AD5206 devices 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 devices are used in mechanical potentiometer replacement, programmable filters, delays and time constants, and line impedance matching. The devices are designed for PCB mounts.
