DESCRIPTION  
The DS1804 NV Trimmer Potentiometer is a nonvolatile digital potentiometer having 100 positions. The  
device 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 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.
