DS1804-100+

DS1804-100+ is a nonvolatile digital trimmer potentiometer that has 100 positions. The device provides an ideal method for low-cost trimming applications using a CPU or manual control input with minimal external circuitry. The wiper position of the DS1804 can be stored in EEPROM memory on demand. The device’s wiper position is manipulated by a three-terminal port that provides an increment/decrement counter controlled interface. This port consists of the control inputs active-low CS, active-low INC, and U/ active-low D. Additionally, the DS1804 will operate from 3V or 5V supplies and is ideal for portable application requirements.
