1 / 7 page 1 of 7 102699 FEATURES Single 100-position taper potentiometer Nonvolatile “on-demand” wiper storage Operates from 3V or 5V supplies Up/down, increment-controlled interface Available in 8-pin (300-mil) DIP, 8-pin (150-mil) SOIC, 8-pin (118-mil) µSOP, and Flip Chip packages Operating Temperature: – Industrial: -40ºC to +85ºC Standard Resistance Values: – DS1804-010 10 k Ω – DS1804-050 50 k Ω – DS1804-100 100 k Ω PIN ASSIGNMENT PIN DESCIPTION H - High-Terminal of Potentiometer L - Low-Terminal of Potentiometer W - Wiper of Potentiometer VCC - 3V or 5V Power Supply CS - Chip Select U/ D - Up/Down Control INC - Increment/Decrement Wiper Control GND - Ground 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 Ω, 50 kΩ, and 100 kΩ. 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.
