DESCRIPTION

The DS1804 NV trimmer potentiometer is a nonvolatile digital 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. 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

DS1804 is available in three resistor grades, which include a 10kW, 50kW, and 100kW. 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 (300mil) DIP, 8-pin (150mil) SO, 8-pin (118mil) µSOP, and the flip-chip package.
