The DS1804 NV Trimmer Potentiometer is a nonvolatile digital potentiometer having 100 positions. The device DS1804 provides an ideal method for low-cost trimming applications using a CPU or manual control input with minimal external circuitry. Wiper position of the DS1804 can be stored in EEPROM memory on demand. The DS1804 device's wiper position is manipulated by a 3-terminal port that provides an increment/decrement counter controlled interface. This port consists of the control inputs CS , INC , and U/ D . The DS1804 is available in three resistor grades, which include a 10 k, 50 k, and 100 k. The device is provided in an industrial temperature grade. Additionally, the DS1804 will operate from 3V or 5V supplies and is ideal for portable application requirements. Three packaging options are available and include the 8-pin (300-mil) DIP, 8-pin (150-mil) SOIC, 8-pin (118-mil) uSOP, and the Flip Chip Package.
