DS1804 datasheet

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 CS, INC, and U/D. The DS1804 is available in three resistor grades, which include a 10kΩ, 50kΩ, and 100kΩ. 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.
