Dual 10kΩ digital potentiometer with 256-tap resolution
The DS1868BS-010+ from Analog Devices is a dual-channel digital potentiometer offering 10kΩ end-to-end resistance with 256 taps per channel, providing 0.4% resolution per step for precision voltage-divider or variable-resistance applications.
Serial interface and cascade feature
A 3-wire serial interface programs the wiper position; the cascade pin (Cascade Pin) allows multiple DS1868 devices to be daisy-chained on the same bus, expanding channel count without extra GPIOs.
