Each of the four independent potentiometers provides 1024 wiper positions controlled via a 2-wire I2C-compatible interface. Nonvolatile EEPROM stores wiper positions, automatically restoring settings at power-up. The device operates from 2.7V to 5.5V in a 24-pin TSSOP package.","working_principle":"The DS1844 uses a resistor ladder network with 1024 tap points per potentiometer. A 10-bit digital word selects the wiper position, connecting the output to the desired tap. The nonvolatile EEPROM stores the wiper position for each potentiometer, ensuring automatic restoration on power-up without host processor intervention. The I2C interface allows individual or simultaneous control of all four potentiometers. Write protection prevents accidental EEPROM corruption.","pin_description":"
