Dual digital potentiometer provides two independently programmable 256-position resistor channels with nonvolatile wiper memory. The device supports 10 kΩ, 50 kΩ, and 100 kΩ resistance options and operates from a 2.7 V to 5.5 V single supply or dual supplies up to ±2.5 V. A SPI-compatible serial interface controls wiper movement, memory storage, readback, and increment or decrement functions. The family is specified for industrial temperature operation from -40 °C to 85 °C in 16-lead SOIC and TSSOP package options.
